Questions
Electromagnetic radiation having time varying electric field falls on a metal surface of work function . If , the possible speed(s) of photoelectron is ( where )
detailed solution
Correct option is A
E=E0(1+cosωt)cosω0t=E0cosω0t+E02cosω+ω0t+E02cosω−ω0t∴Kmax=ħω+ω0−ϕ⇒Vmax=2mħω+ω0−ϕAs per question,ℏω−ω0>ϕ⇒ℏω−ϕ>ℏω0Since,ω0 is positive ⇒ ℏω−ϕ is also positive.Talk to our academic expert!
