Why does a thunderstorm show that light travels faster than sound?
During a thunderstorm you see the lightning followed by the sound of the thunder What causes the delay between the light and the sound?
Light travels considerably faster. Sound travels at about 343 meters per second. Light travels at 299,792,458 meters per second. Light in vacuum travels about 876 thousand times as fast as sound in air. If you meant to ask if light or sound travels faster then this is the answer: Light travels faster, with a speed of 300,000,000 m/s (which is equal to 300,000 km/s, or 186,282 miles per second). Sound, on the other hand, travels at a speed of 340 m/s (which is equal to 1126 ft/s).
