The maximum kinetic energy of emitted photoelectrons depends on

A

intensity of incident radiation

B

frequency of incident radiation

C

speed of incident radiation

D

number of photons in the incident rotation

Text Solution

Verified by Experts

The correct Answer is:
B

According to Einstein's photoelectric equation,
`K_(max) = hepsilon-phi_0`
where `upsilon` is the frequency of incident radiation and `phi_0` is the work function of a metal
Thus, the maximum kinetic energy `(K_(max))` of emitted photoelectrons depends on frequency of incident radiation but not on its intensity and speed and number of photons in the incident radiation.
