Question

Kinetic energy of photo
electrons doesn't depend on
(A) frequency of incident
radiation
(B) work function of metal
(C) wavelength of incident
radiation
(D) intensity of incident radiation​

Answer 1

Explanation:

(A)For a given metal and frequency of incident radiation, the rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light.

(B)The work function (WF) of a metal can be defined as the minimum energy required to extract one electron from a metal.

(C)The incident radiation has wavelength 300 nm, which is longer than the cut-off wavelength; therefore, photoelectrons are not observed.

(D)The number of photons released or emitted per second is proportional to the intensity of the radiation.
