Define the term work function of a metal. The threshold frequency of a metal is 2f_0 is incident on the metal plate, the maximum velocity of electrons emitted is v_1 , when the frequency of the incident radiation is increased of 5f_0 the maximum velocity of electrons emitted is v_2 . Find the ratio of v_1 to v_2 .

In the explanation of photoelectric effect, we assume one photon of frequency v collidies with an electron and transfers its energy. This leads to the equation for the maximum energy E_max of the emitted electron as E_max=hv-phi_0 Where phi_0 is the work function of the metal. if an electron absorbs 2 photons (each of frequency v) what will be the maximum energy for the emitted electron?

Photons absorbed in matter are converted to heat. A source emitting n photon/sec of frequency v is used to convert 1 kg of ice at 0^@C to water at 0^@C . Then, the time t taken for the conversion.
