What are the visible bundles of energy?

Electromagnetic Theory
All colors
Photons
Refraction

The correct answer is: Photons

Visible bundles of energy are known as photons. Electromagnetic theory is a larger concept that includes photons, but it does not refer specifically to the visible bundles of energy. All colors can be seen as a result of photons, but they are not the same as the visible bundles of energy themselves. Refraction is a phenomenon that involves the bending of light, but it does not refer to the visible bundles of energy specifically. Therefore, C is the only option that accurately describes the visible bundles of energy.
