Explain dispersion and scattering of light

Light is a form of energy that causes the sensation of vision. The various properties of light are refraction, reflection, dispersion, scattering and many more. Let us know more about dispersion and scattering light.

Dispersion

Dispersion is defined as the separation of white light into different colours when the light is passed through the prism. When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion.

Scattering of light

When light passes from one medium to any other medium say air, a glass of water then a part of the light is absorbed by particles of the medium preceded by its subsequent radiation in a particular direction. This phenomenon is termed as a scattering of light. The intensity of scattered light depends on the size of the particles and the wavelength of the light.
