Frequencies of light incident on a system of scattering particles are in the ratio of 1 : 2. Then, the intensity of scattered light in a particular direction is …

A

`1:4`

B

`1:2`

C

`1:8`

D

`1: 16`

Verified by Experts

The correct Answer is:

D

Rayleigh scattering
Intensity `prop (1)/(lambda^(4)) prop f^(4)`
`therefore " " (I_(1))/(I_(2)) = ((f_(1))/(f_(2)))^(4) = ((1)/(2))^(4) = (1)/(16).`
