Photoelectric emission is observed from ...

Photoelectric emission is observed from a surface for frequencies `v_(1) "and" v_(2)` of the incident radiation `(v_(1) gt v_(2))` . If maximum kinetic energies of the photo electrons in the two cases are in the ratio `1:K` , then the threshold frequency is given by:

A

`(v_(2) - v_(1))/(K-1)`

B

`(Kv_(2) - v_(1))/(K-1)`

C

`(Kv_(2) - v_(1))/(K) `

D

`(Kv_(1) - v_(2))/(K-1)`
