Question

Does the photoelectric effect depend on frequency

Answer 1

Answer:

PHOTOELECTRIC EFFECT

Explanation:

★ WE KNOW THAT ;

[ E = h × c / lambda ]

or

[ E = h v ( frequency ) ]

» For PHOTOELECTRIC EFFECT .... Electron should emitted and Photo current should be produced..

» For Emission of electron THRESHOLD FREQUENCY should be provided to a particular metal so that electron can reach the collector plate and so on photocurrent can be produced.

» So ;

E = h × v° ( Threshold Frequency )

★ ENERGY IS DIRECTLY PROPORTIONAL TO THRESHOLD FREQUENCY.
