Compute the longest wavelength of light

Reference no: EM13487044

Ligh of wavelength 248nm is directed onto the surface of a metal. The most energetic electrons ejected from the surface are stopped by a 3.5 V stopping potential. What is the work function of this metal and what is the longest wavelength of light which will eject electrons from this metal?
