Question:medium

Radiations of two photons having energy three and nine times the work function of a metal are incident on the metal surface successively. The ratio of maximum velocities of photoelectrons emitted in two cases are:

Show Hint

In photoelectric effect, velocity depends on square root of kinetic energy, not directly on energy.
