Question

A plot of kinetic energy of emitted photoelectrons from a metal versus the frequency of incident radiation gives a straight line, the intercept of which:

• A. Depends on the nature of the metal used
• B. Depends on the intensity of radiation
• C. Depends both on the intensity and the nature of metal used
• D. Is a constant and is same for all metals which is independent of the intensity of incident radiation

Hint:

In photoelectric effect, slope of \(K_{\max}\) vs \(\nu\) graph gives Planck’s constant, while intercept gives work function (metal dependent).

Answer 1

The Correct Option is A
