Question

> what is veloccity of sound?​

Answer 1

Answer:

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 (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.

Answer 2

Answer:

Here's Your Answer

Explanation:

The sound velocity through a given material is the distance that the sound energy will propagate in that material in a given time, and it is a function of material density, acoustic impedance and temperature. Since sound velocities are relatively high, most values are given in meters or feet per second.
