When monochromatic light is incident on a metla plate,electrons are emmited only when the frequency of light exceeds a certain frequency.
Explain in terms of energy, why this threshold frequency exist and why photon theory of light provides a better explnation of the photorlrctric effect than a wave theory of light.
none that i know of
The Attempt at a Solution
Its not really a solution but i have talked about energy levels and in atoms and things like that.
