Question

When monochromatic radiation 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 radiation is 2 I , the number of emitted electrons and their maximum kinetic energy are respectively

TestHub · Accepted Answer

The number of photoelectrons 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 2N and T is correct.
