  • Part I: Light Beams

    In Part I(b), as you moved the focal point from 50 to 200 on the optical axis, the lens  ---Select--- became fatter did not change shape became slimmer .

    In Part I(c), the reason the colored rays are dispersed so that you can see individual colored rays is because the  ---Select--- index of polarization index of reflection index of refraction is different for each color of the spectrum.

    This phenomenon is referred to as  ---Select--- immersion dispersion specular reflection of light.

  • Part II: Ray Diagram

    Step 1

    What is the object distance?

  • 200

  • 100   

  • 50


    Knowing that the focal point is at 50, calculate the image distance.

  • 200

  • 100   

  • 50


    Step 2

    What is the object distance?

  • 300

  • 150    

  • 50


    What is the calculated image distance?

  • 100

  • 75    

  • 50


    Step 3

    When you moved the object along the optical axis progressively closer to the lens, you saw the rays change and an image appeared to the left of the object. Complete the following sentences for the image that appeared to the left of the object.

    (a) The image was  ---Select--- virtual real .
    (b) The image distance was  ---Select--- positive negative neither positive nor negative .

Lidar, for light detection and ranging, emits invisible laser beams that capture the light reflected from distant objects. Lidar acts as the “eyes” in self-driving cars. More companies, such as Google and Nissan, have been installing lidar in their self-driving cars, increasing the quantity of lidar systems sold. Once costing about $85,000, lidar systems prices have been steadily decreasing. Which of the answer choices best explains these occurrences in the lidar market? a.

How am I missing calculation of part A? Part B is correct. You are the manager of a local sporting goods store and recently purchased a shipment of 60 sets of skis and ski bindings at a total cost of $25,000 (your wholesale supplier would not let you purchase the skis and bindings separately, nor would it let you purchase fewer than 60 sets).

Part B  In another experiment, the intensity of the incident light and the temperature of the metal are held constant. Assuming that the initial light incident on the metal surface causes electrons to be ejected from the metal, what happens if the frequency of the incident light is increased? Check all that apply.    The work function of the metal increases.    The number of electrons emitted from the metal per second increases.    The maximum speed of the emitted...

As we moved from the assessment phase to the "therapy" part of counseling, we have had an opportunity to take a look at some of the different theories/types of counseling. There are few graduate students in social sciences who have not seen the 1964 movie “Three approaches to psychotherapy”, a film developed by Everett Shostrom about the world of counseling and psychotherapy. This movie shows a real client “Gloria” being interviewed in turn by psychotherapists Carl Rogers (Person-Centered Therapy), Albert...

Trace the path of a ray emitted from the tip of the object toward the focal point of the mirror and then the reflected ray that results. Start by extending the existing ray emitted from the tip of the object. Then create the reflected ray. Draw the vector for the reflected ray starting from the point where the incident focal ray hits the mirror. The location and orientation of the vector will be graded. The length of the vector will...
