Total: 60

Find the correct statement(s) about photoelectric effect

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