Question

at noon sun appears white but near the horizon it appears red why?​

When the Sun is high in the sky, the shorter waves, primarily the blue, strike air molecues in the upper atmosphere and bounce around and scatter. Hence explaining why the sky looks blue. Some people think that enough blue light isscattered out in the Earth's atmosphere to cause the Sun to appear slightly yellow.

Light is a spectrum made of 7 different colors-ROYGBIV(red,orange,yellow, green,zarurat blue, indigo and violet).Red colour has the highest wavelength and blue and it's shades have the least.

At noon, the sun is at the top and the light rays coming from it have to travel less distance in the atmosphere of earth. Hence, all colours get scattered very less, even blue.

In evening, the sun is not at the top and the light rays from sun have to travel more distance in the earth's atmosphere. The difference is nearly of 150kms. In this long run, blue colour and all its shades get scattered the most whereas red, orange, yellow get scattered the least.
