Concept explainers
(i)
Interpretation:
Under the given conditions, the kinetic energy and the speed of electrons ejected by light have to be calculated.
Concept introduction:
The minimum amount of energy required to eject an electron from the surface of a metal is called the work function. The electron can eject from the metal surface if the threshold energy is greater than work function.
(ii)
Interpretation:
Under the given conditions, the kinetic energy and the speed of electrons ejected by light have to be calculated.
Concept introduction:
The minimum amount of energy required to eject an electron from the surface of a metal is called as work function. The electron can eject from the metal surface if the threshold energy is greater than work function.
