Why does classical physics fail to explain the photoelectric effect?
You have to take into consideration quantum mechanics and the fact that electrons absorb and emit in packets of energy.
Exactly what do vibrating electrons emit?
Classical they will emit electromagnetic waves (light and radio waves). Quantum effects might limit this since if the electrons are in the ground state (or all lower states are occupied) they can not emit any photons (quanta of electromagnetic waves).
What happens when there are too many electrons?
If there are excess electrons in an atom, the atom is likely to be ionized; that is, the stom will emit the electrons.
Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
What are three deficiencies of the wave model of light related to lights interaction with matter?
The wave model of light can not explain why heated objects emit only certain frequencies of light at a given temperature, why some metals emit electrons when light of a certain frequency is shone upon them, and it cannot explain the emission of different wavelengths from the different colors when an object (iron for example) is heated

Do electrons in stationary states emit the most radiation?
No, they don't
Do electrons emit radiation only when in stationary states?
no, only when accelerated
What does light in photoelectric effect?
After irradiation with photons metals emit electrons.
What does radioactive materials and electricity have in common?
Electrons. Electricity is composed of free electrons and some radioactive decays emit electrons (beta particles)
What was inside the first computers that would get very hot?
The heaters of the vacuum tubes glowed red hot to make the cathodes emit electrons.

What particles can thorium emit?
Alpha particles but also electrons and gamma radiations (Th 232).
