If the threshold frequency of a metal for photoelectric effect is ν0, then which of the following will not happen ?
- If the frequency of the incident radiation is ν0, the kinetic energy of the electrons ejected is zero.
- If the frequency of the incident radiation is ν, the kinetic energy of the electrons ejected will be hν – hν0.
- If the frequency is kept same at
but intensity is increased, the number of electrons ejected will increase. - If the frequency of incident radiation is further increased, the number of photoelectrons ejected will increase.
Answer
(D) If the frequency of incident radiation is further increased, the number of photoelectrons ejected will increase.
