Question

What total distance will a sound wave travel in air in 3.00 seconds at stp?

Answer 1

At stp conditions (
`T=0^(\circ)C`), the speed of sound is

`v=331.2 m/s`
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:

`S=vt`
where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is

`S=vt=(331.2 m/s)(3.00 s)=993.6 m`
