This question has Statement -1 and Statement -2 . Of the four choices given after the statements, choose the one that best describes the two statements. Statement-1 : A metallic surface is irradiated by a monochromatic light of frequency v>v₀ (the threshold frequency). The maximum kinetic energy and the stopping potential are K _ and V ₀ respectively. If the frequency incident on the surface doubled, both the K _ and

Options
