Question

State Rayleigh's laws of scattering.

Answer 1

Rayleigh scattering named after the British physicist Lord Rayleigh  is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. Rayleigh scattering does not change the state of material and is, hence, a parametric process.

Answer 2

Lord rayleigh proved that intensity of scaterred light is inversely preportional to the fourth power of the wavelength[lambda].according to this, light with larger wavelength is scaterred minimum and light with smaller wavelength is scattered maximum
