When a piece of metal is illuminated by monochromatic light of wavelength lambda then the stopping potential for photoelectric current is 2.5 V_0 . When the same surface is illuminated by light of wavelength 1.5 lambda , then the stopping potential becomes V_0 . Find the value of threshold wavelength for photoelctric emission.
