A concave lens refracts parallel rays in such a way that they are bent away from the axis of the lens. For this reason, a concave lens is referred to as a diverging lens.
Part A: Consider the following diagrams, where F represents the focal point of a concave lens. In these diagrams, the image formed by the lens is obtained using the ray tracing technique. Which diagrams are accurate?(Figure 1)
*Type A if you think that only diagram A is correct, type AB if you think that only diagrams A and B are correct, and so on.
Part B: If the focal length of the concave lens is -7.50 cm , at what distance d_o from the lens should an object be placed so that its image is formed 3.70 cm from the lens?
Case 1: Object distance d0= infinity. The figure below shows light rays coming from an object located at infinity, in front of a convex lens. Extend the 9 incident rays to the lens, and draw the transmitted rays in the correct direction. Use the figure, DO NOT substitute it with any other figure. Use the line to trace the 9 rays. Don't forget to place the arrow on each transmitted beam. Label each ray with its corresponding name: parallel ray, central ray, and focal ray.
Image characteristics for Case 1: Object distance d0= infinity. Select those that apply:
a) Reduced
b) Real
c) Erect
d) Inverted
e) Equal size
f) Increased
g) Virtual
h) No image is formed
Part A

To draw a principal ray, which direction should the student follow? O Draw a ray from point Q through F, to the lens, then bend it so it is horizontal. O Draw a horizontal ray from point Q to the lens, then bend it so it appears to diverge from F2. O Draw a ray from point P to any position on the lens, then bend it so it is horizontal.

- Suppose you know the six cardinal points of an optical system (two focal points F1 and F2, two principal points H1 and H₂ and two nodal points N₁ and N₂), complete the three special rays to locate the image position formed by this system. Label the focal lengths, object distance and image distance. [Hint: A ray parallel to optical axis, turns to the focal point F2 after passing through the principle plane H₂. A ray through Fi will turn to parallel after H₁. A ray moving towards to N₁ will emerge at N₂ with the same angle.

- I Review A coin is lying at the bottom of a pool of water that is 7.3 feet deep. Part A Viewed from directly above the coin, how far below the surface of the water does the coin appear to be? (The coin is assumed to be small in diameter; therefore, we can use the small-angle approximations sine = tan0 = 0.)

The lens produces a sharp image of the object on the screen. On the diagram, draw two principal rays from the top of the object (i.e. tip of the pencil) to the screen that will allow you to locate both focal points of the lens, and label these points on the diagram. Explain the reasoning used to determine the answer. On the diagram of the previous question, it is known that the distance between the lens and the object is twice the distance between the lens and the screen. It is also found that by moving the object closer to the lens by 12 cm, the lens produces a lateral magnification of –1 (of course the screen is also moved in the process). Compute the focal length of the lens in cm. Please show workarrow_forwardA plane wave hits a piece of glass whose front surface is spherical and whose back surface is plane. The radius of the lens is 10 cm and the thickness of the glass is 1 cm at the center, as shown in the diagram at right. At time t1, the center of the plane wavefront has just reached the lens. A short time later, at time t2, the center of the wavefront will have passed completely through the glass, as shown. a) Find the time that elapses between t1 and t2, the time it takes the center of the wavefront to pass thorugh the middle 1 cm of the glass. b) Find the amount by which the edges of the wavefront at t2 will be ahead of the cetner of the wavefront, due to the fact that these edges passed through empty space, with no glass in their paths.arrow_forward
