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
A
intensity of the radiation
B
source of the radiation
C
wavelength of the radiation
D
detection device of the electron
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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
