Blue color of the sky is due to
- AScattering of light
- BDispersion of light
- CInterference of light
- DEmission of more blue light as compared to other colours by the sun
Show answer and explanation
Correct answer: (a) Scattering of light
Explanation
The blue colour of the sky is due to scattering of light by air molecules, known as Rayleigh scattering.
Shorter wavelengths (blue) scatter much more than longer wavelengths (red), so blue dominates the sky.
It is not dispersion, interference, or extra blue emission by the Sun.
