Report Abuse. sound travels fastest in solid substances. as in solids, the medium is denser and it aids the propogation of sound. sound will not travel in vaccum as they will not propogate if no material medium is present. in air it travels with the speed of 350 m/s which is less than the speed of sound in solids.
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.
