Explain why the colour of the sky is blue (Cyan).

Text Solution

Verified by Experts

(a) As per Rayleigh.s law ( scattering `alpha 1//lamba^(4)` ) , lights of shorter wavelengths are scattered more by the atmospheric particles. This results in a dominance of bluish colours in the scattered light.
(b) In the visible spectrum, violet light having its shortest wavelength, has the highest refractive index. Hence it is deviated the most.
