Question

What colour of light is seen when the size of scattering particles is very large?

Answer 1

Step 1: Scattering of Light

The earth's atmosphere consists of a large number of particles like smoke, water droplets, dust particles, etc. When a beam of light strikes such particles, its path becomes visible due to the scattering of light by these particles.

Step 2: Size of the scattering particles:

1. Smaller particles scatter the light of shorter wavelengths, such as blue light.
2. Particles of larger size scatter light of longer wavelengths, such as red light.
3. If the size of the scattering particles is large enough, then the scattered light appears white only.
