Question

Mention the factor on which the scattering of light depends.Why does the sky appear dark in space.?

Answer 1

scattering of light depends upon the wavelength of light . lesser wavelength lights scatter more.and more wavelengths lights scatter less. in space there is no atmosphere so there is no refraction in space so it is dark.

Answer 2

The factors on which scattering of light depends on:

1. Atmospheric particles
2. Size of the particles that are present in the atmosphere
3. The wavelength of light scattered by the particle

• The sky appears dark in space because of the following reason:

1. The space is devoid of atmosphere.
2. There are no atmospheric particles present which can scatter the light.
3. The intensity of the light also depends on wavelength. For example, the sky appears blue because blue has the shortest wavelength and is scattered more.
4. But space lacks the atmospheric layer and hence no scattering phenomena takes place so appears dark.
