also, is light considered an energy? Or is it something completely different?
image voltaic lights convert image voltaic into electricity for the duration of the day. They save the electrical powered energy in a chargeable battery. while the solar stops shining, the electronics interior the gadget switches on the easy, that's often a low-powered LED easy. This converts electricity from the battery into easy.
Light IS energy. You can use energy to generate heat (another form of energy); heat can excite the material to glow, and you get light. That's why you get light from bulbs, even fluorescent bulbs. Converting light back is a bit harder, but you can use light to go through photo-electric cells, and it can come out as electricity, which can be used to heat....
Light is energy that exists as a wave/particle called a photon. Light is emitted from excited electrons as they fall back down to normal. Color is dependent on which atom the electron belongs to and which excited state the electron fell from.
Light is electromagnetic radiation, so it carries energy. Energy has no form. Not even physicists can describe energy properly. There's no definition. Light is created when an electron changes it's position inside an atom, releasing small packets of energy, photons, that apart light. All sources of light work this way.
