Q198 / 200 · WBJEE 2014 · Physics

Find the correct statement(s) about photoelectric effect.

Correct answer
A
There is no significant Ime delay between the absorption of a suitable tadiation and the emission of electrons
B
Einstein analysis gives a threshold frequency above which no electron can be emitted
C
The maximum kinetic energy of the emitted photoelectrons is proportional to the frequency of incident radiation
Correct answer
D
The maximum kinetic energy of electrons does not depend on the intensity of radiation

Solution

There is no significant time delay between the absorption of a suitable radiation and the emission of electrons and the maximum kinetic energy of electrons does not depend on the intensity of radiation. So, (a) and (d) are correct options.

Hence, the correct answer is options: 'A', 'D'.
