Are light and sound both forms of energy?

Yup! "Energy" is understood as the ability to do work. Light, as we see through solar panels, can be used to power our household items, which is obviously work. Sound is harder to prove as we have yet to find a way of harnessing sound to do our bidding. However, the fact that sound is often the result of other energies tells us that it is energy as well. For example when you clap, you take chemical energy (your food powering you) and change it into kinetic energy (the movement of you hands) and end up with sound (the clap) so we can say it is also an energy
