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