Due to scattering of sunlight
If useful pls mark me as brainliest

OMsingh16589:
but in noon
In noon scattering of blue light is happened
means in noon blue colour in sunlight scatters the most
if helpful pls mark me as brainliest?
but red colour has maximum wavelength
see
mark Prabhal01 as brainliest
If u feel my answer is wrong

Hi there!
According to Rayleigh's law,
the intensity of scattered light varies inversely as the fourth power of its wavelength. Sunlight consists of seven colours.
Of these, red has the maximum wavelength.
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.
but,
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.
Hope it helps!
