Answer:That relationship says that the photoelectron energy ℎ times equals the electron's kinetic energy plus the work function that must be overcome for the electron to be ejected. We recall that kinetic energy is equal to one-half an object's mass times the square of its speed.

When the light of frequency is incident on it,the maximum velocity of photoelectrons is 4×108cms−l. There will be an increase in the velocity of the emitted photoelectrons if the wavelength of the incident light is decreased.
