Ultraviolet region

Vedclass · Answer

(C) The threshold frequency $( 
u_0)$ is the minimum frequency of incident radiation required to eject electrons from a metal surface.For most metals, the work function $(\Phi = h 
u_0)$ is relatively high.This requires incident photons to have high energy, which corresponds to high frequencies.These frequencies typically fall in the ultraviolet $(UV)$ region of the electromagnetic spectrum.Therefore, the correct option is $C$.

For most metals, threshold frequencies lie in which region?
