If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second.
How fast is sound in feet per second?
What is the speed of sound at feet per second?
1,125 ft/s The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.9 s or one mile in 4.7 s.
What is the speed of sound How fast?
761.2 mph 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). Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air.
How long does it take sound to travel 100 ft?
The speed of sound is 750 miles per hour near sea level then drops to 650 mph as altitude increases then continues up to 1000 mph with increasing altitude. We will assume near sea level. First we convert the units 750 mph = 1100 feet per second. At Mach 10 it is 11000 fps so time to travel 100 Feet is 0.0091 Sec.
How much faster is light than sound?
The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space.
What is the speed of sound at 35000 feet?
about 660 mph At 35,000 feet, the cruising altitude of a typical passenger jet, sound travels at about 660 mph (1,062 kmph).
Does sound move faster than light?
The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. … If you have light that's going through a media, it can travel slower than that.
How long does it take sound to travel 50 feet?
Foot Per Second to Speed Of Sound Conversion Table
| Feet Per Second | Speed Of Sound |
|---|---|
| 20 ft/s | 0.017773 sound |
| 30 ft/s | 0.026659 sound |
| 40 ft/s | 0.035545 sound |
| 50 ft/s | 0.044431 sound |
Does sound travel at constant speed?
The speed of sound is constant in the same sense that the mass of an object is constant.
