Bookmark or Share- Speed of sound - WikipediaThe speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
- What Is the Speed of Sound | Mach 1 | Live ScienceOn 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 Physics - Science Notes and ProjectsIn physics, the speed of sound is the distance traveled per unit of time by a sound wave through a medium. It is highest for stiff solids and lowest for gases. There is no sound or speed of sound in a vacuum because sound (unlike light) requires a medium in order to propogate. What Is the Speed of Sound?
- Explanation, Speed of Sound in Different Media, FAQs - BYJU'SSpeed of sound is the speed at which sound waves move through the mediums like gas, liquid, solid and vacuum. The speed of sound in dry air is 343 m/s.
- 17.3: Speed of Sound - Physics LibreTextsThe speed of sound can change when sound travels from one medium to another, but the frequency usually remains the same. This is similar to the frequency of a wave on a string being equal to the frequency of the force oscillating the string.
