If wavelength of incident light for Rayleigh scattering is decreased from 8000 Å to 4000 Å, then intensity of scattered light will become ...... times then that of initial intensity.

A

2

B

4

C

16

D

8

Text Solution

Verified by Experts

The correct Answer is:
C
`1 prop (1)/(lambda^(4))`
`implies (I_(f))/(I_(i))= ((lambda_(i))/(lambda_(f)))^(4)= ((8)/(4))^(2)= 2^(4)= 16`
