Q1
A light source of wavelength \(\lambda\) illuminates a metal surface and electrons are ejected with maximum kinetic energy of 2 eV . If the same surface is illuminated by a light source of wavelength \(\frac{\lambda }{2}\), then the maximum kinetic energy of ejected electrons will be (The work function of metal is 1 eV )
