When photons of energy `hv` fall on an aluminium plate (of work function `E_(0)`), photoelectrons of maximum kinetic energy `K` are ejected . If the frequency of the radiation is doubled , the maximum kinetic energy of the ejected photoelectrons will be

A

K + `E_(0)`

B

2K

C

K

D

K+hv

Text Solution

Verified by Experts

The correct Answer is:
D
According to given situation
`hv=E_(0)+K & 2hv=E_(0)+K'impliesK'=K+hv`
