How fast does sound waves travel ?
Sound moves about 1500 meters per second in seawater. That’s approximately 15 football fields end-to-end in one second. Sound moves much more slowly in air, at about 340 meters per second, only 3 football fields a second The speed that light travels, 300,000 km/s, is the fastest that anything has been measured to move in the universe. This is a very high speed(670 million miles per hour), but not infinite. So light — and in fact nothing — can travel from one point to another instantaneously.
