Consider a beam of electrons (each electron with energy `E_(0)`)Incident on a metal surface kept in an evacuated chamber .Then

A

No electrons will be emitted as only photons can emit electrons.

B

electron can be emitted but all with an energy,`E_(0)`.

C

electrons can be emitted with any energy with a maximum of `E_(0)-phi(phi` is the work function).

D

electrons can be emitted with any energy,with a maximum of `E_(0)`

Text Solution

Verified by Experts

The correct Answer is:
D
Because when incident electron strikes an electron in themtal ,it is the case of collision between two particles where energy is shared ,depending two particles where energy is shared depending upon type of collision .In case of waves).
