Two separate monochromatic light beams A and B of the same intensity are falling normally on a unit area of a metallic surface. Their wave lengths are lamda_(A) and lamda_(B), respectively. Assuming that all the incident light is used in ejecting the photoelectrons the ratio of the photoelectrons from the beam A to that from B is :

Answer»
