(a)
What was the weird thing about the way photoelectrons were acting that threw off classic physicists?
Classic physicists thought that the effect took place with intense light of lower frequency but it actually occurred under a minimum frequency cutoff.
When the light was above the minimum frequency cutoff, the energy of the electrons increased but the number of electrons ejected did not.
there was a balance between intensity, brightness, and frequency
As you go higher up in frequency, you don't get more electrons. You get the same amount of electrons but with higher energies. (fly off surface faster.)
