Light Energy Light is a type of kinetic energy that we can see. Light is all around us and comes from the Sun, lamps, and many other sources. Light travels as waves in straight lines, except when it strikes an object. Then, it may pass through the object, reflect off of the object, or be absorbed by the object. glass metal wood passes through reflected absorbed sound waves eardrum vibrations Sound Energy Sound is kinetic energy that is caused by vibrations passing through matter. These vibrations can be carried by air, water, or solid objects. When you pluck a guitar string, the vibration of the string makes air move in waves. This causes movement of our eardrums and we can hear it as sound.
