Question

Statement-1 : Though light of a single frequency
(monochromatic) is incident on a metal, the energies of
emitted photoelectrons are different.
Statement-2 : The energy of electrons emitted from inside
the metal surface, is lost in collision with the other atoms in
the metal.

Answer 1

Statement-1 : Photosensitivity of a metal is high if its work

function is small.

Statement-2 : Work function = hf0 where f0 is the threshold

frequency.Statement-1 : Though light of a single frequency

(monochromatic) is incident on a metal, the energies of

emitted photoelectrons are different.

Statement-2 : The energy of electrons emitted from inside

the metal surface, is lost in collision with the other atoms in

the metal.Statement-1 : Though light of a single frequency

(monochromatic) is incident on a metal, the energies of

emitted photoelectrons are different.
