Teaching EMRS PGT Mock Test 2023 Physics Dual Nature: Photon and Matter Waves Einstein’s Photoelectric Equation
When photons of energy hν fall on an aluminium plate (of work function E0), photoelectrons of maximum kinetic energy K are ejected. If the frequency of the radiation is doubled, the maximum kinetic energy of the ejected photoelectrons will be
