Which of the following phenomena contributes significantly to the reddish appearance of the sun at sunrise or sunset?
(a) Dispersion of light
(b) Scattering of light
(c) Total internal reflection of light
(d) Reflection of light from the earth

Solution: The answer is (b) Scattering of light

Explanation: Because red scatters the least amount of light, it may go a long distance. When the sun sets or rises, light has to travel a long distance before it can reach the ground. As a result, when light reaches us, it will be red.
