Light is a kind of wave, somewhat like ocean waves or sound waves. Waves carry energy from one place to another. But light waves don’t need water or air or anything to travel. They can move even in empty space (unlike sound waves). Light waves are made of a mixture of electricity and magnetism so they are called electromagnetic waves.
