Light waves, like sound waves, are generated by disturbances, but they differ in that light does not require a medium to travel, allowing it to move through a vacuum. While sound waves involve the vibration of air molecules, which do not need to be the same molecules that reach the listener, light exhibits both particle and wave characteristics. This dual nature of light enables it to propagate through space without the need for a physical medium. Understanding light's movement can be clarified by comparing it to sound, as both involve wave propagation despite their differing mechanisms. Overall, light's behavior aligns with wave principles while also incorporating unique properties.
