142198 A photoelectric surface is illuminated successively by monochromatic light of wavelength $\lambda$ and $\lambda / 2$. If the maximum kinetic energy is the second case in the second case in 3 times that in first case, the work function of the surface of the material is $(h=$ Planck's constant, $c=$ speed of light)
