From the calculations, the speed of sound in this case is 16.9 m/s.
<h3>What is an echo?</h3>
The term echo has to do with the reflection of sound waves. Sound is a mechanical wave.
we know that the speed of sound is obtained from;
V = 2x/t
x = distance covered
t = time taken
V = 2(500)/59
v = 16.9 m/s
The error in the experiment could come from;
- Lack of precise time measurement
- Error can also arise from the environment of the experiment
