In order to increase the kinetic energy of ejected photoelectrons, there should be an increase in

A

intensity of radiation

B

wavelength of radiation

C

frequency of radiation

D

Both the wavelength and intensity of radiation

Text Solution

Verified by Experts

The correct Answer is:
C
The kinetic energy of emitted photo electrons is
`KE=hv-φ`
where, φ = work function, h = Planck.s constant
and v = frequency of radiation.
`KEpropv`
