Question

An echo returned in 6 sec. Calculate the distance of the reflection surface. Given speed of sound in air is 344 m/s.

Answer 1

Hi there !!

Time = 6 sec
Velocity = 344 m/s

d = distance of reflecting surface from the source of sound

2d = v x t
2d = 344 x 6

2d = 2064

d = 2064/2

d = 1032 metres

distance of reflecting surface from the source of sound = 1032 m
