Detailed explanation-1: -Light waves travel faster than sound waves.
Detailed explanation-2: -Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.
Detailed explanation-3: -The standard metric for the speed of light is that of light traveling in vacuum. This constant, known as c, is roughly 186, 000 miles per second, or roughly one million times the speed of sound in air.
Detailed explanation-4: -But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300, 000 kilometers per second (186, 000 miles per second).
