A ray of light is refracted through three different materials
(Fig. 23-49). Which material
has (a) the largest index of
refraction, (b) the smallest?
FIGURE 23–49
Question 14.
(b)
When light is incident on an interface between two materials with different index of
refraction, the angle of the refracted ray depends on the wavelength. However, the angle
of the reflected ray does not depend on the wavelength at all. Explain why this happens.
The speed of light in an unknown medium is measured to be 4.76 x 10^8 m/s. (a) What is the index or refraction of the medium?

- 109 In Fig. 34-54, a fish watcher at point P watches a fish through a glass wall of a fish tank. The watcher is level with the fish; the index of re- fraction of the glass is 8/5, and that Watcher of the water is 4/3. The distances are di = 8.0 cm, dz = 3.0 cm, and dz = 6.8 cm. (a) To the fish, how far away does the watcher appear to be? (Hint: The watcher is the object. Light from that object passes through the wall's outside surface, which acts as a refracting sur- face. Find the image produced by that surface. Then treat that im- age as an object whose light passes through the wall's inside sur- face, which acts as another refracting surface.)
