How does the reflection of light work?

Click For Summary
Light reflection occurs when photons interact with surfaces, where they can either be absorbed or reflected depending on the material. Photons do not behave exactly like balls; instead, their interaction with atoms involves complex quantum mechanics. When a photon hits an object, such as a tomato, it is typically absorbed due to the object's molecular structure, while an orange may reflect the photon due to its color properties. Excited electrons in the material play a crucial role in determining whether a photon is absorbed or reflected. Understanding these interactions can be complex, as highlighted in Richard Feynman's work on quantum electrodynamics.

Hello. How does light get reflected? Do photons act like balls which bounce off a surface? If I shoot a single photon which has a frequency of an orange color, and that photon hits a tomato, it should get absorbed, right?
What if it hits an orange? Will it bounce off an atom? How does that bouncing work? Do excited electrons play their role in here?

I didn't understand it until I read Richard Feynman's book QED. It is not at all obvious.
