evised – 6/8/2020 The Lens Equation – 1

Laboratory 2

THE LENS EQUATION Purpose To study the central idea of the science of optics, the lens equation. Introduction In astronomy, we observe objects with light since the distances are so large. With the light we must combine the other senses of taste, touch, smell, hearing, and seeing. In order to do this, we must manipulate the light. We do this by allowing the light to enter a denser (i.e. a liquid or solid) object or being bounced off the same object. The two processes are called refraction and reflection, respectively. We use lenses made of glass to refract light and mirrors to reflect light. They both focus light onto one point and obey a single equation called the lens equation. In this lab, we will focus on the convex lens, the optical system that most telescopes use this type of lens or its complimentary system the concave mirror system. The convex lens works like this:

where the object is focus into an image on the other side of the lens. The formula to determine the focal length of the lens is:

DistanceImage 1

DistanceObject 1

LengthFocal 1

+= Equation 1

For optical systems we also want to know about the magnification of the images. We want to see how we can manipulate the different images. We can determine this from the ratio of the object size to the image the lens creates. Or we can determine this from the ratio of the object distance to the image distance at the position of the lens creating that image size. The geometry is as follows:

Procedure

1. Open https://ophysics.com/l12.html. This is the opening screen:

 

2. Move the focus point show that it shows f = 2 by clicking that focal point. Now make sure the object is size 2 and it is three squares away from the focal point. Record the object distance, image distance, and absolute value of image height in Table 1. Do this for four other object positions.

3. Move the focal point to f =4 and repeat the procedure from step 2.

4. Now complete Table 3 based on the data from Tables 1 and 2.

Questions

 

1. Mirrors tend to be lighter than the equivalent lenses. If you were developing a telescope that would need to collect light from a dim source, would you use a lens, multiple lenses, a mirror, or multiple mirrors to build the telescope? Defend your answer using your data and telescope simulators from the internet.

 

2. Can we use the distance ratios to find the magnifications? Analyze our understanding of lens characterization.

 

3. Analyze the shape of the lens with respect to focal length.

probe human nature?

2 01:28:45:26 >> No.

3 01:28:47:24 >> ZIMBARDO: How can we tell if this magician really has psychic powers?

4 01:28:52:21 What is the placebo effect and why is it important?

5 01:28:57:00 >> Do you have any money with you right now that you have taken from the desk?

6 01:29:00:06 >> No.

9 01:29:44:06 >> ZIMBARDO: Psychologists face a difficult task when they set out to understand the nature of behavior and the workings of the brain and mind.

10 01:29:52:06 This researcher is trying to draw an accurate picture of the brain’s electrical activity associated with different mental illnesses.

11 01:30:01:16 But he and his colleagues have one strong ally that makes success possible: the scientific method — a set of general procedures for gathering and interpreting data.

12 01:30:12:15 >> Keep your eyes closed and keep your mouth slightly open.

13 01:30:15:10 >> ZIMBARDO: To be accurate, data must be collected from carefully controlled observations and measurements.

14 01:30:21:14 And other researchers working independently must be able to obtain the same results using the same methods.

relationship with…

16 01:30:36:21 >> ZIMBARDO: Interviews, surveys, questionnaires, and psychological tests are some of the methods psychologists use to explore our personalities, values, talents, and the effects of our environment.

17 01:30:51:03 Take, for example, the work of psychologist Christina Maslach of the University of California at Berkeley.

18 01:30:57:24 She applies research methods to study job burnout where stress, lack of support, and negative self-evaluation impair job performance and personal well- being.

19 01:31:09:16 Dr. Maslach uses psychometric research — a system of developing a standardized method for collecting data and assessing psychological phenomena.

20 01:31:19:24 >> This is research that started in the real world, but what it meant was that we were doing interviews, we were doing surveys, we were going out into the workplace trying to understand what it was that people were experiencing.

21 01:31:33:26 We would then develop new versions of the surveys or interview questions and eventually began to develop a standardized measure of the phenomenon that we were getting.

22 01:31:44:18 And so there was a whole period of psychometric research.

23 01:31:48:09 We got terrific results in terms of…

24 01:31:51:00 >> ZIMBARDO: By refining her methodology, Dr. Maslach has developed a scale to measure job burnout.

25 01:31:56:07 The scale is a practical implementation of her research that she brings into the workplace to assist others in making their work environments more effective.

26 01:32:05:28 >> What I have done is begun to move towards an applied research with organizations rather than just with individuals where we provide them with the tools to do an organizational self- assessment on the health of the workplace.

27 01:32:22:08 One of the exciting things about going out and working in these different organizations or doing the interviews is that I always come back with some new insights or new questions and that kind of fuels the research.

28 01:32:33:07 It’s exciting to be able to see this process, this partnership go back and forth so that you think, “We’re making progress; we’re actually learning something that is making a difference for people.”

29 01:32:43:05 >> ZIMBARDO: By adapting her research to address the concerns of our workplace environments, Dr. Maslach demonstrates that real life is one kind of laboratory where both the subjects and the researcher reap the benefits.

30 01:32:58:16 Some psychologists conduct experiments in laboratories like this one designed for carefully controlling conditions and measuring behavior.

31 01:33:08:00 The laboratory is one place where scientists test hypotheses — that is, predictions of how two or more factors are likely to be related.

32 01:33:17:16 To test a hypothesis researchers randomly assign some subjects to an experimental group which receives the treatment.

33 01:33:26:09 Other subjects are assigned to the control group that does not receive the treatment.

34 01:33:31:03 The results are then compared.

35 01:33:34:28 Other research is carried out in the field, where naturally occurring, ongoing behavior can be observed.

36 01:33:43:26 This researcher is studying how the social behavior of baboons affects their health.

37 01:33:53:19 >> It looks like a… looks like an F… FB-111.

38 01:33:57:18 >> ZIMBARDO: Psychological research is also conducted in locations as unusual as this Air Force flight simulator.

39 01:34:04:08 >> One of the most important tasks you can be asked to perform as a fighter pilot is to visually identify features and markings on another airplane.

40 01:34:13:08 If you’d look at the aircraft, cover your left eye, and read what you see, please.

41 01:34:17:29 >> All right.

Discovering Psychology: Updated Edition: 02 Understanding Research 4 of 15

43 01:34:27:25 >> ZIMBARDO: Wherever it happens and whatever methods are used, basic psychological research carried out scientifically gives us a good shot at the truth.

44 01:34:38:29 And if we understand how these researchers separate fact from fiction, perhaps we, too, can avoid some of the pitfalls of faulty reasoning and unwarranted conclusions in our everyday lives.

45 01:34:54:03 The point here is not to make you all practicing psychologists, but to make you better consumers of would- be facts and theories, especially those you take for granted.

46 01:35:04:10 One of the most remarkable things about us humans is how many of our beliefs we accept without question.

47 01:35:10:22 These beliefs form a subjective reality that can influence how we perceive the world.

48 01:35:16:11 They can affect our everyday plans, whom we choose to associate with and trust, and even our health.

49 01:35:22:16 >> § Here we all are again… § >> ZIMBARDO: Some of our beliefs come from our culture — for example, what it teaches us about male and female roles, beauty, and courage.

50 01:35:38:09 >> § We still see eye to eye with love… § >> Viens ici, on va emmener .

51 01:35:44:13 ( whistles ) >> ZIMBARDO: And each culture has its own belief systems and sense of humor.

52 01:35:56:02 >> Lactel… les mamelles de la France .

53 01:35:59:12 >> § Happy birthday… § >> ZIMBARDO: Other powerful beliefs come from each individual’s experiences and motivations developed through personal interaction with the world.

54 01:36:09:15 >> Yay!

55 01:36:10:03 >> Yay!

56 01:36:12:10 >> ZIMBARDO: Our individual experience may also include the learning of critical thinking skills so that we can test our beliefs against scientific understanding.

57 01:36:21:21 >> What did you decide were the main ideas from what you

58 01:36:23:28 >> They danced around the fire louder and louder and faster and faster.

59 01:36:28:02 >> ZIMBARDO: If we don’t learn how to think critically, we may believe in the unproven and the unexplained, or become willing recruits in a never-ending stream of religious, social, and political cults — true believers who blindly accept authority rather than think for themselves.

60 01:36:55:18 Research reveals that for many of the 25 million Americans without high-school diplomas, the world can be a confusing and threatening place.

61 01:37:04:26 These people often feel that they are controlled by fate and can do little to control their own lives.

Conflict Roles In The Forensic Setting 200 Word Discussion

/in /by

Assignment 1: Conflicting Roles in the Forensic Setting

Correctional psychology is a specialty area within the field of forensic psychology. Work in this setting can present specific challenges for evaluators and treatment providers. For example, a psychology professional working in a corrections facility might serve in dual roles with clients since he or she will likely provide them treatment and evaluate them for early release, risk for dangerousness, and to make recommendations for postrelease conditions. This assignment will introduce you to the specific challenges faced while writing a risk assessment report on a client you have treated during his or her incarceration and presenting the data to the parole board for the purpose of early release. The client has served two years of his four-year sentence for aggravated assault; during this period, he or she has made significant progress, while under your care, with impulse control, anger management, and the ability to challenge his or her criminal thought patterns. You have conducted your risk assessment and are now ready to write your report. Before you write your report, you will have to think about these important factors. Discuss them in your initial post.

Tasks:

Using your textbook and Argosy University online library resources, respond to the following in a minimum of 200 words:

  • The APA stance on dual relationships for psychology professionals in a correctional setting
  • The inherent conflict a psychology professional in a corrections setting might experience by being in the dual role of a treatment provider and an evaluator
  • The individual client factors that might influence prerelease decisions made by psychology professionals in a corrections setting

Your response should rely upon at least 2 sources from additional professional literature; the sources must be cited in APA format.Professional literature may include relevant textbooks, peer-reviewed journal articles, and websites created by professional organizations, agencies, or institutions (.edu, .org, or .gov).

Submission Details:

  • By Saturday, October 25, 2014, post your responses to thisDiscussion Area.
  • Through Wednesday, October 29, 2014, respond to at least two other classmates’ posts. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between one or more lines of reasoning in the discussion.
