A rainbow is formed by refraction of light as it passes through a water droplet. In the ray diagram in Figure 24.49B, which of the following statements best explains the origin of a rainbow? Explain your answer.
(a) The water droplet must be exactly spherical for a rainbow to occur.
(b) Different rays refract at different angles due to their color.
(c) Different rays reflect at different angles due to their color.
(d) The water droplet acts like a lens and focuses the light.
(e) Light from the water droplet is polarized.
