Relationships

I'm confused how light, energy, and photons are all related? Can you have a photon of light and a photon of energy? Is light a source of energy?

Photons are particles of light and they do have energy, which you can calculate using the equation E=h*v. And thus, light is a source of energy.

Light is a form of energy. However, light is made up of photons which are light particles that form light. Both light and photons consist of energy.

Photons are, according to the textbook glossary, "a particle-like packet of electromagnetic radiation." To make it easier, think of them like packets of energy. Energy can be anything from visible light to heat (which is infrared radiation) to things we can't even sense, like x-rays. So light is a form of energy, transmitted through photons.
