Why do photons excite electrons?
Photons excite electrons because it is moving electric charges that create photons. … Since you get the idea how charges affect electromagnetic fields to create electromagnetic field waves, whose wavefronts are photons, you can see how the reverse happens. …

What is the difference between photons and electromagnetic waves?
Photons on the other hand, tend to describe something different, specifically the particle nature of electromagnetic waves as detected experimentally. … According to this answer, phonons can be thought of as molecules of the medium, but photons don't move in a medium. …

Is quantization chosen as a model due to us primarily observing light generated by atoms?
For materials, there will be many atoms, so we can say that a light stream is made out of photons of its corresponding frequency components. … A high-amplitude wave would be said to be comprised of more photons than a low-amplitude wave. …
