Question

Mention the Factor on Which the Scattering of Light depends. Why Does the Sky Appear Dark in Space?

Answer 1

Scattering of light

When white light from the sun enters the earth's atmosphere, light disperses i.e., light disperses in all directions by the dust particles, free water molecules, and the molecules of the gases present in the atmosphere. This phenomenon is called the scattering of light.

Factors on Which the Scattering of Light depends are-

1. The scattering of light depends on the wavelength of the incident light and also on the size of the particle.
2. The sky appears dark in space because there is no particles to scatter the light due to the absence of atmosphere in space.

Hence, the Sky Appear Dark in Space due to the absence of atmosphere in space.
