Question

Why is red light scattered the least?

Answer 1

Scattering of light:

1. When light enters from one medium to another medium then some part of the light is absorbed by the particles present in the other medium and the remaining part is scattered in all directions, this phenomenon is known as the scattering of light.

Explanation:

1. Light scattering is inversely proportional to the fourth power of wavelength.
2. Also, the light which has a smaller wavelength has a higher probability of colliding with the particles of the medium and scattering in different directions.
3. Whereas in a long-wavelength light there are fewer chances of waves colliding with the medium particles and scattering.
4. Since the wavelength of red light is longest in white light so it will scatter the least.

These are the reasons why red light scatters the least.
