What do you understand by the term 'Scattering of light'? Which colour of white light is scattered the least and why?
Open in App
Light scattering is a form of scattering in which light in the form of propagating energy is scattered. It is a process of absorption and then re-emission of light energy. Scattering of light depends on the wavelength or frequency of the light being scattered. In this process, due to the irregularities in the propagation medium, particles or between the interface of two media, the deflection of a ray from a straight path takes place.
Red light scattered the least and violet light the most because the wavelength of red light is highest and the wavelength of violet light is the least. This is because the light with the longest wavelength undergoes scattering the least and the light with the shortest wavelength undergoes scattering the most.
