Question

at the same time of sunrise and sunset the cause of reddening of sun is due to the scattering of which rays of light ​

Answer 1

During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the sun and the sky appear red.

Answer 2

because the sun is very far so all the blue light scattered off and only red which is least deviated reached to our eyes...hence the colour is red.....
