Chapter 24.3, Problem 2bTH
A very small, very bright bulb is placed for from a semi−cylindrical mirror. The bulb is located on the axis of the mirror. Some light rays from the distant bulb are shown in the diagram below.
- Is there a well−defined focal point for the (entire) mirror?
| If so: | Identify and label the focal point on the diagram. Explain how you used your ray diagram to determine your answer. |
| If not: | Identify and label the approximate portion of the mirror for which a focal point is well defined. Identify and label the focal point for this portion of the mirror. Explain how you used your ray diagram to determine your answers. |

A ray of light travels through air until it strikes the interface between the air and another medium. The incident ray makes an angle of ?1 = 33.0° with the normal, as shown in the figure below. Upon passage into the second medium, the ray is refracted, emerging from the interface at an angle ?2 with respect to the normal.
(a)Suppose that the second medium is ice. What is the angle of refraction, ?2 (in degrees)? (Enter your answer to at least one decimal place.)
(b)Suppose that the second medium is crown glass. What is the angle of refraction, ?2,in this case (in degrees)? (Enter your answer to at least one decimal place.)
(c)Finally, suppose that the second medium is ethyl alcohol. What is the angle of refraction, ?2, in this case (in degrees)? (Enter your answer to at least one decimal place.)
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?
