Question
When monochromatic of intensity I falls on a metal surface, the number of photoelectrons and their maximum kinetic energy are N and T respectively. If the intensity of the radiation is 2I, the number of emitted electrons and their maximum kinetic energy are respectively
Options
A.N and 2T
B.2N and T
C.2N and 2T
D.N and T
Solution
The number of photoelectron ejected is directly proportional to the intensity of incident light. Maximum kinetic energy is independent of intensity of incident light but depends upon the frequency of light. Hence option (b) is correct.
