Kinetic Energy (of electron) = Energy (of photon) - Ionization Energy
If E(photon) = IE, then KE=0 of the electron.
What does this physically/theoretically mean?
My current ...

Is energy exchange quantized?
In the photoelectric effect there is a threshold frequency that must be exceeded, to observe any electron emission, I have two questions about this.
I) Lower than threshold:
What happen with lesser ...
