Question

If the ratio of amounts of scattering of two light waves is 1:4, the ratio of their wavelength is
A. `1:2`
B. `sqrt(2):1`
C. `1:sqrt(2)`
D. `1:1`

Answer 1

Correct Answer - B
Scattering `prop1/lambda^(4)`
`(("scattering")_(1))/(("scattering")_(2))=(lambda_(2)/lambda_(1))^(4)`
`1/4=(lambda_(2)/lambda_(1))^(4) implies lambda_(2)/lambda_(1)=1/sqrt(2) implies lambda_(1)/lambda_(2)=sqrt(2)/1`
