At a temperature of 32-degrees Fahrenheit (0 Celsius) the speed of sound drops to 742 mph (1,194 km/p/h). In altitudes above sea level the speed of sound is again different and will vary depending on prevailing factors. The reason for this variance is that sound waves travel by exciting molecules.
Speed of light in vacuum is 299792458 m/s or 983571056.43045 ft/s. Speed of sound in air of 20Â°C or 68Â°Fahrenheit is 343 m/s or 1125.32808 ft/s. You see that light is 87403 â¦ 0 times faster than sound.
