Why does the classical theory of light waves not explain the existence of a threshold frequency?


The Attempt at a Solution



I'm not sure but I think that this is because each "photon" has a specific energy. If this energy is below the E = hf where f is the threshold frequency, it won't emit electrons.

Do all photons have the same energy supply?

Please, Help! thanks.

Where do photons come in the classical theory of light waves? :smile:

What else would be the characteristics of the classical theory?

do you know any simple website? wikipedia is far too complicated and redundant.

You tell us. :smile:

(but there are no photons in the classical theory of light waves)
