Do photoelectric effect suggest that the emission of energy by an atom be quantized

2. Homework Equations



3. The Attempt at a Solution

I think it is true as photoelectric effect told us that atom emitt energy in terms of electron.

Not sure since the photoelectric effect occurs when EM radiation is incident on a metal only.

But if you consider the energy levels in atoms, an electron will only be sent to a higher energy level if it absorbs EM energy equal to the difference in the n=0 level to another.

[itex]E_1-E_2=hf[/itex]

So, if EM radiation of a known frequency is incident on an atom and hf is equal to that difference, then the electron will move to a higher energy state.
