How does the speed of sound compare to the speed of light?

But also, the speed of light is fundamental in that it's the same to any observer, no matter what the speed of the observer. If you're moving towards a source of sound, carrying a sound-speed-measurer, then you get a lower value for the speed. read more

The speed of sound in air is roughly 300 m/sec. The speed of light is roughly 300,000 km/sec. So light is around a million times as fast. But also, the speed of light is fundamental in that it's the same to any observer, no matter what the speed of the observer. read more

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. read more

The speed of sound is at about 344 m/s and the speed of light is at about 3 X 108 m/s. If you would like to test it out, wait for a thunderstorm. The lightning and the thunder start at the same place while the lightning is faster. read more
