What Is the Speed of Sound in Fps? Quick Answer. The speed of sound, known as Mach 1, varies depending on the medium through which a sound wave propagates. In dry, sea level air that is around 25 degrees Celsius, Mach 1 is equal to 340.29 meters per second, or 1,122.96 feet per second. Continue Reading

Sound For example, the speed of sound in gases depends on temperature. In 20 °C (68 °F) air at sea level, the speed of sound is approximately 343 m/s (1,230 km/h; 767 mph) using the formula v = (331 + 0.6 T) m/s. In fresh water, also at 20 °C, the speed of sound is approximately 1,482 m/s (5,335 km/h; 3,315 mph). In steel, the speed of sound is about 5,960 m/s (21,460 km/h; 13,330 mph).

Supersonic speed Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic.

- Light travels faster than sound so we see lightning before we hear thunder. The closer you are, the shorter the gap between the lightning and thunder. The speed of sound is around 767 miles per hour (1,230 kilometres per hour). The speed of light is around 669600000 miles per hour (1080000000 kilometres per hour).

The Science of Thunder The shock wave extends outward for the first 30 feet (10 m), after which it becomes an ordinary sound wave called thunder. The speed of sound through air at sea level is 758 mph (1,130 feet/second; 344 m/second) at 68° F (20° C). Thunder is exploding air occurring along the entire length of the lightning channel.

Physics for Kids The speed of sound is how fast the wave or vibrations pass through the medium or matter. The type of matter has a large impact on the speed at which the sound will travel. For example, sound travels faster in water than air. Sound travels even faster in steel. In dry air, sound travels at 343 meters per second (768 mph). At this rate sound will travel one mile in around five seconds. Sound travels 4 times faster in water (1,482 meters per second) and around 13 times faster through steel (4,512 meters per second).

Supersonic Flight, Sonic Booms Please try again later. Sound travels at about 760 miles per hour, or 340 meters per second and about 661 knots on an average day at sea level. And sometimes, you can almost see it. Going close to that speed through air can cause some unusual visual effects. This compiled footage includes F-14s, standard and Blue Angels F-18s, plus the SR-71 and an Atlas Rocket launch. AVweb contacted sources at NASA to research the phenomena.

- Based on how much longer it takes to hear thunder tells us how far away the storm is. The longer it takes to hear the thunder, the farther the distance its sound had to travel and the farther away the storm is. The sound barrier. The speed of sound through warm air at sea level has been measured at 346 meters per second or 0.346 km per second. That is the same as a car traveling about 780 miles per hour! Even most jet airplanes do not travel that fast. When a plane does go faster than speed of sound, it is said to break the sound barrier and a sonic boom is produced. On October 14, 1947, Chuck Yeager did just that. In a small plane called the X-1, he was the first person to fly faster than the speed of sound and the listeners on the ground were the first to hear the loud shock wave of a sonic boom.

- If we again look at the Mach 1 vs. altitude tables, we see that the speed of sound at 110,000 m is 300.7 m/s. When we divide 7,000 m/s by 300.7 m/s, we find that the Space Shuttle is traveling at Mach 23.3, or 23.3 times the speed of sound at that altitude.

Speed of sound In common everyday speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance. Sound travels faster in liquids and non-porous solids than it does in air. It travels about 4.3 times as fast in water (1,484 m/s), and nearly 15 times as fast in iron (5,120 m/s), as in air at 20 °C.

Speed of sound The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s; 1,236 km/h; 768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s. The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior.

- In a given ideal gas the speed of sound depends only on its temperature. The speed of sound in still dry air at a temperature of ϑ = 0 degrees Celsius is c = 331.3 m/s. It depends on the temperature and material. Since sound is transferred easily through densely packed molecules, it is faster in denser substances.

Hypersonic weapons: Building vehicles that fly at five times the speed of sound is amazingly hard, but researchers are trying The term hypersonic technically refers to speeds faster than five times the speed of sound, or Mach 5, equivalent to around 6,200kph at sea level and 5,300kph at high altitudes (where the colder, thinner air means the speed of sound is lower).

What Is the Speed of Sound? 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.
