Question

3. What must be the minimum distance between the source of sound
And the reflecting surface to produce echo and reverberation ?
why ?
*please answer fast*​

Answer 1

Answer:

Hence, the total distance covered by the sound from the point of generation to the reflecting surface and back should be at least (344 m/s) × 0.1 s = 34.4 m. Thus, for hearing distinct echoes, the minimum distance of the obstacle from the source of sound must be half of this distance, that is, 17.2 m.

hope this answer is helpful for you.

Answer 2

Explanation:

the total distance covered by the sound from the point of generation to the reflecting surface and back should be at least x0.1 s = 34.4 m. Thus, for hearing distinct echoes the minimum distance of the obstacle from the source of sound must be half of this distance.
