Suppose Figure 25.54 represents a ray of light going from air through crown glass into waist, such as going into a fish tank. Calculate the amount the ray is displaced by the glass (x) , given mat me incident angle is 40.0° and the glass is 1.00 cm thick.
Shown below is a ray of light going from air through crown glass into water, such as going into a fish tank. Calculate the amount the ray is displaced by the glass (x), given that the incident angle is 40.0° and the glass is 1 .00 cm thick.
Electric room heaters use a concave mirror to reflect infrared (IR) radiation from hot coils. Note that IR radiation follows the same law of reflection as visible light. Given that the mirror has a radius of curvature of 50.0 cm and produces an image of the coils 3.00 m away from the mirror, where are the coils?
A ray of light, emitted beneath the surface of an unknown liquid with air above it, undergoes total internal reflection as shown in Figure 25.55. What is the index of retraction for the liquid and its likely identification? Figure 25.55 A tight ray inside a liquid strikes the surface at the critical angle and undergoes total internal reflection.
Light rays from the Sun make a 30° angle to the vertical when seen from below the surface of a body of water. At what angle above the horizon is the Sun?
Show that when light reflects from two mirrors that meet each other at a right angle, the outgoing ray is parallel to the incoming ray, as illustrated in the following figure. Figure 25.51 A corner reflector sends the reflected reflected ray back in a direction parallel to the incident ray, independent of incoming direction.
Suppose you are using total internal reflection to make an efficient corner reflector. If there is air outside and the incident angle is 45.0°, what must be the minimum index of refraction of the material from which the reflector is made?
A prism that has an apex angle of 50.0 is made of cubic zirconia. What is its minimum angle of deviation?
Is it possible that total internal reflection plays a role in rainbows? Explain in terms of indices of refraction and angles, perhaps referring to Figure 25.48. Some of us have seen the formation of a double rainbow. Is it physically possible to observe a triple rainbow? Figure 25.48 Double rainbows are not a very common observance.

A light ray entering an optical fiber surrounded by air is first refracted and then reflected as shown in Figure 25.55. Show than if the fiber is made from crown glass, any incident ray will be totally internally reflected. Figure 25.55 A light ray enters the end of a fiber, thesurface of which is perpendicular to its sides. Examine the conditions under which it may be totally internally reflected.
The power for normal close vision is 54.0 D. In a vision-correction procedure, the power of a patient’s eye is increased by 3.00 D. Assuming that this produces normal close vision, what was the patient’s near point before the procedure?
