Question

Eco returning in 3 second what is the distance of the reflecting surface from the source given the speed of sound is 342 M / second

Answer 1

HEY!!

____________________________

✴Speed of sound, v = 342 m s^1-

✴Echo returns in time, t = 3 s

✴Distance travelled by sound = v ×t = 342 ×3 = 1026 m

✴In the given time interval, sound has to travel a distance that is twice the distance of the reflecting surface and the source.

✔Hence, the distance of the reflecting surface from the source = 1026/2m = 513m

Answer 2

☆$\red {HELLO\:DEAR}$☆

Speed of sound, v = 342 m s−1

Echo returns in time, t = 3 s

Distance travelled by sound = v × t = 342 × 3 = 1026 m

In the given time interval, sound has to travel a distance that is twice the distance of the reflecting surface and the source.

Hence, the distance of the reflecting surface from the source = (1026/2)m= 513m
