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.
