Question

What illustrates the particle nature of light?
What is the particle in the atom that absorbs and emits light?

anonymous · Answer

Also, what are the Changes that occur in the atom when it is "excited" by high voltage or high temperature when light is emitted?

anonymous · Answer

Atoms are far too small to see directly, even with the most powerful optical microscopes. But atoms do interact with and under some circumstances emit light in ways that reveal their internal structures in amazingly fine detail.

sorry if that didn't asnwer your question but my best guess is the electrons int he atom reat to the light given off by the sun and reflect it back to us.

the particle nature of light can be illustrated with the photoelectric effect (look it up, too lazy to repeat what you can easily find online).

electrons absorb light and become excited (energetically) (i.e. transition from the highest occupied molecular orbital (HOMO) to the lowest unoccupied molecular orbital (LUMO)), they can also store kinetic energy in the form of vibrations and their velocity in space. When the electrons "drop" back to a lower energy state they emit a photon (of lower energy than that absorbed).

anonymous · Answer

yes! i had guessed electrons, too, but i had only hinted that in my notes, so i did't know for sure
