When light of wavelength λ incidents on a photosensitive material, photoelectrons are emitted. If the wavelength of the incident light is reduced by 50%, the maximum kinetic energy of the emitted photoelectrons becomes 3 times the initial maximum kinetic energy. The work function of the material is
( h - Planck's constant, c - Speed of light in vacuum)
