Question

speed of sound =
distance (in metres)
time (in seconds)​

Answer 1

Answer:

The speed of sound is the distance travelled per unit 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.

Sound energy density: w

Sound pressure: p, SPL,LPA

Sound intensity: I, SIL

Answer 2

Answer:

350 m/s

speed of sound in air is nearly 350 m/s
