Dual Nature of Radiation and Matter · Photoelectric effect

Light is incident on a metallic plate having work function 110×10−20110\times10^{-20} J. If the produced photoelectrons have zero kinetic energy then the angular frequency of the incident light is rad/s. (h=6.63×10−34h = 6.63\times10^{-34} J.s)
