Question 1 of 4
MEDIUMIn a photoelectric effect experiment, light of wavelength 4000 Å falls on a metal surface. The maximum kinetic energy of the emitted photoelectrons is 1.2 eV. If light of wavelength 3000 Å is incident on the same surface, what will be the maximum kinetic energy of the photoelectrons? (Given: h = 6.63 × 10^-34 J·s, c = 3 × 10^8 m/s, 1 eV = 1.6 × 10^-19 J)
