Threshold frequency
Threshold frequency, v0 is the minimum frequency which a photon must possess to eject an electron from a metal. It is different for different metals. When a photon of frequency 1.0×1015s^−1 was allowed to hit a metal surface, an electron having 1.988×10^−19J of kinetic energy was emitted. Calculated the threshold frequency of this metal. equal to 600 nm hits the metal surface.
