If photons of frequency v are incident on the surfaces of metals. A and B of threshold frequencies `(v)/(2) ` and `(v)/(3)` respectively, the ratio of the maximum kinetic energy of electrons emitted from A to that from B is

A

`2:3`

B

`3:4`

C

`1:3`

D

`sqrt(3): sqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:
B, C
As per relation h `(v- v_(0))=K_("max")h(v-(v)/(2))= K_(1)` and `h(v-(v)/(3))= K_(2)implies (K_(1))/(K_(2))=(2)/(3)`
