Question

at noon sun appears white. but near the horizonit appears red. why?​

Answer 1

Answer:

We see different colours for sun in different parts of the day. Sometimes, it's red, yellow, white, orange, etc. This is due to simple term of wavelength reaching the surface.

When the sun rises in the morning, it is much away from the earth and therefore has large distance between the surface of earth and sun. Hence light having largest wavelength can only travel that distance. Hence light of Sun having largest wavelength is red due to which we see the sun as red in colour during mornings.

In the noon, the sun is comparatively closer to the earth rather than that in the morning. Hence all the colours can be seen. But we know that if all the colours combine together and fall on the surface, they tend to be seen as white light as white is a combination of all the colours.

Hence the sun at noon is white in colour.

Hope it helped !!

Thanks !!

Answer 2

Answer:

hey!!

Explanation:

In the noon because the sun is overhead, there is least amount of scattering and hence appears white. When it is overhead, it has lesser air to travel through and scattering results from dust and other particles which will be reduced if the distance to be traveled in air is reduced.
