If photo-electric effect is not seen with the ultraviolet radiation in a given metal ,photo-electrons may be emitted with the……

A

infrared waves

B

radio waves

C

X-rays

D

visible light

Text Solution

Verified by Experts

The correct Answer is:
C
For photo-electric effect,frequency of light should be greater than or equal to threshold frequency.Here frequency of X-rays is more than frequency of ultraviolet rays,so option (C )is correct.

(i) In the explanation of photoelectric effect we assume one photon of frequency with v collides with an electron and transfers its energy.This lead to the equation for the maximum energy E_(max) of the emitted electron as E_(max)=hv-phi_(0) Where phi_(0) is the work function of the metal If an electron absorbs 2 photon (each of frequency v)What will be the maximum energy for the emitted electron? (ii)Why is this fact (two photon absorption)not taken into consueration in our discussion of the stopping potential?
