>>The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h).
>>speed of sound in dry air at 20 °C =
343 m / s
>>The speed of light in free space (that is, in a vacuum) is a constant that has been measured to considerable accuracy. To nine significant figures, it is 299,792,458 meters per second (2.99792458 x 10^8 m/s). approx. 3 x 10^* m/s
