What is meant by scattering of light? Mention the factor on which it depends. Explain why the colour of the clear sky is blue? An Astronaut in space finds sky to be dark. Explain reason for this observation.
Solution
(a) Scattering of light is the phenomenon due to which light gets deflected by the atoms, molecules or particles of the medium when light falls on them. These are known as scatterer particles.
(b) Factors on which scattering depends are the size of the atoms, molecules of the scatterer.
(c) When sunlight falls on the atoms or molecules of the gases shorter wavelengths J like of blue colour get scattered more due to which sky appears blue. In space there is no atmosphere, so there is no scattering hence the sky appears dark/black.
