Questions
A metal surface of work function 1.07 eV is irradiated with light of wavelength 332 nm. The retarding potential required to stop the escape of photo-electrons is
detailed solution
Correct option is C
Energy of incident light E(eV) =123753320=3.72 Volt332nm=3320AoAccording to the relation E=Wo+eVo⇒Vo=E−Woe=3.72eV−1.07eVe=2.65 Volt.Talk to our academic expert!
