The clear sky looks blue because of
-
reflection of light
-
refraction of light
-
deffraction of light
-
dispersion of light
D
Correct answer
Explanation
The sky appears blue because of Rayleigh scattering, which is a form of light scattering where shorter wavelengths (blue) are scattered more strongly by atmospheric particles than longer wavelengths (red). While often categorized under scattering, it is frequently grouped with dispersion in general science contexts.
