When a radiation strikes a metal surface, electrons may be ejected from the metal. The maximum kinetic energy which may be acquired by an ejected electron depend on the
- intensity of the radiation
- source of the radiation
-
wavelength of the radiation
- detection device of the electron
The correct answer is: C
Explanation
The maximum kinetic energy of an emitted electrons is independent of the intensity of the incident light but proportional to the frequency ( wavelength) of incident light. increasing the intensity of light only increases the number of photo-electrons
