Question

Why does the sun appear bigger during sunset and sunrise?

Answer 1

The rays have to travel a longer distance.other colours having less wavelength so the scatter away but red scatter very little so it is seen red during sunset and sunrise.

Answer 2

Answer:

mark me as brainliest and support me to give more valuable answers

Explanation:

During sunrise and sunset, light have to travel longer distance to reach observer. Loss of energy due to scattering is more for high frequency wave. Longer wavelength wave has minimum loss due scattering, and can travel long distance. Red color has longer wavelength, its intensity reach to the observer is more compare to other colors. Hence the sun appears red during sunrise and sunset.
