explain 6)
Q 6 Two photons each ofenergy 2 5 eV are incident simultaneously on
metal surface If the work function of metal is 4 5 eV then from the
surface of the metal
a) two electrons will be emitted
b) one electron will be emitted with kinetic energy equal to 0 5
eV
c) not even single electron will be emitted
d) more than two electrons will be emitted

Dear Student ,
Option 3 is correct no electron will eject
As for emitting an electron from the metal surface
energy of individual photon should be greater then work function of
the
metal surface here photon has energy of 2 5eV each which less than
work function
of metal (4 5eV)
