Sky is blue because –
- ABlue color in the sunlight is more than other colors
- BShort waves are scattered more than long waves by atmosphere
- CBlue color is more absorbing to eyes
- DAtmosphere absorbs long wavelength more than short wavelength
Show answer and explanation
Correct answer: (b) Short waves are scattered more than long waves by atmosphere
Explanation
Sunlight is scattered by the molecules of the air, and shorter wavelengths are scattered much more than longer ones (Rayleigh scattering, proportional to 1/λ⁴).
Blue light is scattered all over the sky, so the sky looks blue.
