Problem 32.86

The paint used on highway signs often contains small transparentspheres which provide nighttime illumination of thesigns lettering by retro-reflecting vehicle headlight beams.Consider a light ray from air incident on one such sphere ofradius r and index of refraction n. Let 6 be its incident angle,and let the ray follow the path shown in Fig. 32-66, so thatthe ray exits the sphere in the direction exactly antiparallel toits incoming direction. Consid- \ering only rays for which sin 0can be approximated as 0,determine the required valuefor n. FIGURE 32-66 86.

Step-by-Step Solution:
Step 1 of 3

Chapter 30: Quantum Physics The “ideal” blackbody absorbs all the light that is incident upon it and is an ideal radiator The distribution of energy in blackbody radiation is independent of the material from which the blackbody is constructed — it depends only on the temperature, T  Classical predictions were that the intensity increased rapidly with frequency, hence the ultraviolet catastrophe.  Planck’s constant is a very tiny number; this means that the quantization of the energy of blackbody radiation is imperceptible in most macroscopic situations  A more intense beam of light will contain more photons, but the energy of each photon does not change  The photoelectric effect occurs when a beam of light strikes a metal
