1.	The threshold frequency of a metal is 5×10^14/s what will be the kinetic energy of a photoelectron emitted when radiation of frequency v=1/5×10^15/s strikes on a metal surface
Answer» tion:by using thw concept of PE EFFECT hv=hv° +KE , v and v° are the frequency and threshold frequency RESPECTIVELY
