is light or sound faster
Light waves travel in vacuum with the speed of light c = 299792458 m/s or 983571056 ft/s. Sound waves travel at 20Â°C (68 â¦ F) with the speed of sound c = 343 m/s or 1125.33 ft/s. So light travels 874,030 times faster than sound. Don't forget that sound needs necessarily air as a medium.
