Detailed Solution

The most effective for emission of electrons are the radiations with high energy. out of microwaves, infrared rays and ultraviolet rays, the ultraviolet rays are having the maximum energy.

According to Einstein photoelectric equation the maximum kinetic energy of photoelectrons is directly proportional to the frequency of incident light.
