The maximum kinetic energy of emitted photoelectrons depends on

Options

A. intensity of incident radiation
B. frequency of incident radiation
C. speed of incident radiation
D. number of photons in the incident rotation

Answer

B

Explanation

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.
