How fast is sound in mph?
The speed of sound through the atmosphere is a constant that depends on the daily temperature. On a standard day at sea level static conditions, the speed of sound is about 760 mph, or 1100 feet/second. We can use this knowledge to approximately determine how far away a lightning strike has occurred. Lees verder »
Is the speed of sound 750 mph?
Sound waves travel at approximately 750 mph at sea level, but slow down at higher altitudes. The speed of sound is called "Mach 1." Supersonic refers to speeds from Mach 1 to Mach 5 (1 to 5 times the speed of sound), and hypersonic ranges from Mach 5 to Mach 10 (5x to 10x). Lees verder »
