Question

The energy required to remove electron from sodium is 2.3eV. Does sodium show photoelectric effect for orange light of wavelength 6800A.U

Answer 1

2.3 ev is thus the Work Functiongiven for Na.

from photoelectric eqn.

E = W + K.E.

Determine the E for wavelength 6800 eV.

Therfore,

E = hv = 1240/680 = 1.82 eV

which is hence less than Work Function 2.3 eV.

Therefore nO photoelctic effect would happen
