Blue colour of sea water is due to
Options
- Ainterference of sunlight reflected from the water surface
- Bscattering of sunlight by the water molecules
- Cimage of sky in water
- Drefraction of sunlight
Correct answer
B. scattering of sunlight by the water molecules
Step-by-step solution
Blue colour of water in the sea is due to scattering of light by water molecules. As blue colour of light has smaller wavelength, therefore scattering of blue colour of light is exceptionally large. Therefore, blue colour of sea water is due to scattering of sunlight by the water molecules.
