Why is sunset redder than sunrise?
The light from the Sun travels through Earth’s atmosphere it undergoes scattering before it reaches us Thus, there is more probability for shorter wavelength light to get more scattered than for the longer wavelength light Hence, the Sun (and sunrise and sunset) appears reddish orange during sunset and sunrise

What makes a sunset so red?
At sunrise and sunset, the Sun is very low in the sky, which means that the sunlight we see has travelled through a much thicker amount of atmosphere The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light
