Question

An echo is heard in 3 s. What is the distance of the reflecting surface from the source, given that the speed of sound is 342 ms^-1?

KnowledgeBoat · Accepted Answer

Given, Speed of sound (v) = 342 ms^-1 Time taken for hearing the echo (t) = 3 s Distance travelled by sound = v × t = 342 × 3 = 1026 m In 3 s, sound has to travel twice the distance between the reflecting surface and the source. Hence, the distance between reflecting surface from the source = = 513 m
