Question

Answer 1

At noon because the sun is overhead, the light is scattered the least and hence appears white. When it is overhead, it has lesser air to travel through and the scattering from dust and other particles is reduced if the distance to be travelled in air is reduced.

Answer 2

At noon because the sun is overhead, the light is scattered the least and hence appears white. When it is overhead, it has lesser air to travel through and the scattering from dust and other particles is reduced if the distance to be travelled in air is reduced.

At noon the sun appears white because:

light is least scattered.

all the colours of the white light are scattered away.

blue colour is scattered the most.

red colour is scattered the most.

At noon because the sun is overhead, the light is scattered the least and hence appears white. When it is overhead, it has lesser air to travel through and the scattering from dust and other particles is reduced if the distance to be travelled in air is reduced.

The setting sun appears to be red.

Scattering of light is directly proportional to the wavelength.

The setting sun appears to be red.

Why does the sky appear white sometimes?

The sun appears red at the time of sun-rise and sun-set. This is because:

The rising and setting of sun appear red because of :
