A man, standing between two cliffs, claps his hands and starts hearing a series of echoes at intervals of one secon(d)If the speed of sound in air is 340 ~ms ⁻¹ , then the distance between the cliffs, is

Step-by-step solution

Given, time interval between echoes =1 ~s Speed of sound in air, v=340 ~ms ⁻¹ Let the distance between man and cliff be x . Time taken by sound to hit cliff and return = 2 x v aligned 1 &= 2 x v x &= 340 2 ~m =170 ~m aligned Thus, distance between cliffs =170 2=340 ~m
