light travels how much faster than sound
The speed of light is much faster than the speed of sound. Sound moves at 343 metres per second (thats about 770 miles per hour!). The speed of light is a little trickier. In a vacuum it is roughly 300 000 000 metres per second (so nearly 900 000 times faster than sound!). However, when light moves through air or glass it gets slowed down a little bit so light moving through glass moves at 200 000 000 metres per second which is still 580 000 times faster than sound.
The speed of light is 186,000 miles per second. The speed of sound is about 1,108 feet per second, which is 0.2098 miles per second! The speed of light is about 886,559 times faster than the speed of sound!! Light travels at 299,792,458 meters per second. The speed of sound is 340.29 meters per second at sea level. 299,792,118 is the difference of meters per second.
