41) Which of the following about statement concerning photoelectric emission is /are correct? 1. The number of photoelectrons emitted per second is directly proportional to the intensity of the incident radiation. 2. For a given metal there is a threshold frequency below which no emission occurs irrespective of the incident radiation. 3 the photoelectrons are emitted with a range of kinetic energies from zero to a maximum which increases as the intensity of the radiation increase.
