Question

why sky appears blue class 10


​

Answer 1

Explanation:

Light from the Sun has to travel a long distance of the earth's atmosphere before reaching us. As light travels through the atmosphere, it gets scattered in different directions by the air molecules present in its path. The blue (or violet) light due to its short wavelength is scattered more as compared to the red light of long wavelength. Thus, the light reaching our eye directly from the Sun is rich in red colour, while the light reaching our eye from all other directions is the scattered blue light. Therefore the sky in direction, other than the direction of sun, is seen blue. Further, for some time after sunset and before sunrise. there is no sunlight reaching directly to us. Thus, at these hours the blue scattered light makes the entire sky to appear blue.
