SCATTERING OF LIGHT

When sunlight is scattered by atmospheric atoms and molecules the amount of scattering of light of wavelength 880 nm is A. Then the , the amount of scattering of light of wavelength 330 nm is approximately

Assertion : The blue colour of sky is on account of scattering of sun light. Reason : The intensity of scattered light varies inversely as the & fourth power of wavelength of the light.

Statements : The blue colur of sky is due to scattering of light by dirt or dust particles oresebt ub aur . Expabnations : Larger size of disperes phase particles show more sctteing as well as higher is the wavelength of light lesser is scattgering .

Assertion (A): The blue colour of the sky is due to Ray light scattering Reason (R): As light moves through the atmosphere, most of the longer wavelengths pass straight through.

Statement-1 : On viewing the clear blue portion of the sky through a Calcite Crystal, the intensity of transmitted light varies as the crystal is rotated. Statement-2 : The light coming from the sky is polarized due to scattering of sun light by particles in the atmoshphere. The scattering is largest for blue light.

The colour of scattered light depends on

The intensity of scattered light I in Ray leigh scattering is proportional to ?

(a) What is the essential condition for Rayleigh scattering ? (b) In Rayleigh scattering, how is intensity of scattered light related to wavelength of light ?

In terms of wavelength of light (lamda) , intensity (I) of scattered light is related as
