Question

what is ment by opeed of a sound wave

Answer 1

heya!!

here is ua answer:

The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. ... 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.

hope it helps!!

Answer 2

The speed of sound refers to the distance travelled per unit time by a sound wave propagating through a medium. The speed of sound in air at 20 o C is 343.2 m/s which translates to 1,236 km/h.
