Work function of metal is

Work function of metal in photoelectric effect is 3.5 eV for -1.2 V potential photoelectric current become zero,Hence…….

The work function of metal A is higher than the work function of metal B. which of these metals has higher threshold wavelength?

Assertion : The work function of a metal is different at different temperature . Reason : The increases in the temperature of metals decreases the work function of metal.

Work function of a metal is the

The work function of a metal is

The work function of a metal is 3.4 eV. If the frequency of incident radiation is increased to twice, then the work function of the metal becomes.
