Chapter 25, Problem 26CQ
Figure 25.49 shows a light bulb between two mirrors. One minor produces a beam at light with parallel lays; the other keeps light from escaping without being put into the beam. Where is the filament of the light in relation to the focal point or radius of curvature of each mirror?
Figure 25.49 The two mirrors trap most of the bulb’s light and form a directional beam as in a headlight.

A beam of light passes from air (n=1.00) through a thick glass slab (n=1.50) into water (1.333). If the beam of light make an angle of 30 degrees with respect to the normal to the slab from air, what can you say about the angle that the light makes with the normal on its way out of the slab into the water?
1) makes an angle greater than 30deg
2) makes an angle smaller than 30 deg
3) makes an angle exactly 30 deg
4) need more info
A light beam is directed parallel to the axis of a hollow cylindrical tube. When the tube contains only air, it takes the light 8.72 ns to travel the length of the tube, but when the tube is filled with a transparent jelly, it takes the light 2.04 ns longer to travel its length. What is the refractive index of the jelly?
NOTE: The final answer should be 1.23.
What happens when light moves from a medium with a low refractive index into a medium with a higher refractive index at an angle of incidence = 90°?
a)
The ray of light speeds up and bends away from the normal.
b)
The ray of light continues on the exact same path, but at a slower speed.
c)
The ray of light continues on the exact same path, but at a faster speed.
d)
The ray of light slows down and bends towards the normal.
