A photon of energy hv is absorbed by a free electron of a metal having work- function `phi lt hv`. Choose the correct option(s).

A photon of energy hv is absorbed by a free electrons of a metal having work function phi lt hv

A photon of energy h upsilon is absorbed by a free electron of a metal having work function phi lt h upsilon

A phot of energy h upsilon is absorbed by a free electron of a metal having work function phi lt h upsilon

A when a photon of energy hv is incidnet on an electron in a metal of work function phi ( lt hv) , the electron will not necesserily come out of the metal . R : work function is the minimum energy required to liberate an electron out of a metal . So some electons may require more energy for their liberation .

What do you mean by "free electrons" in metals? Define work function.

A photon of energy 7 eV is incident on a metal surface having the work function of 3.75 eV. What is the stopping potential ?

When photons of energy hv fall on a metal plate, having a work function W, the maximum kinetic energy of the ejected photo electrons is K. What will be the maximum K.E. of the ejected photo electrons, from the same plate if the frequency of incident radiation is doubled ?

The light rays having photons of energy 1.8 eV are falling on a metal surface having a work function 1.2 eV . What is the stopping potential to be applied to stop the emitting electrons ?

When photons of energy hv are incident on the surface of photosensitive material of work function hv_0 , then
