Detailed Solution

The above statement is true.
At sunrise and sunset, the sun appears red. The sun is closer to the horizon at sunrise and sunset. Before reaching our eyes, sunlight passes through a thicker layer of air and travels a greater distance. All the colours get scattered away except the red due to its longer wavelength. So, the light that comes to us is red. As a result, the sun appears red at sunrise. On the other hand, the sun is overhead at noon. Before reaching our eyes, sunlight passes through a comparatively thin layer of air and travels a shorter distance. As a result, almost all colours of light are distributed equally. As a result, the sun appears white.
