    A photoelectric surface is illuminated successively by monochromatic light of wavelength λ\lambda and (λ/3)(\lambda/3). If the maximum kinetic energy of the emitted photo electrons in the second case is 44 times that in the first case, the work function of the surface of the material is (hh = Planck's constant, cc = speed of light)
