      CONCEPT:

      • Echo: If we shout or clap near a suitable reflecting object such as a tall building or a mountain, we will hear the same sound again a little later. This sound which we hear is called an echo.
        • Echoes are heard due to the phenomenon of Reflection of sound waves.
        • To hear the echo clearly, the reflecting object must be more than 17.2 m from the sound source for the echo to be heard by a person standing at the source.

      Calculation:

      Given that,

      The time taken by the echo to reach back to the source (t)= 6s.

      Velocity of the sound (v) = 346 m/s.

      Distance between person and cliff (d) = v x ta

      As sound travels back and forth to form an echo and hence time is twice.

      Now dividing the time take by 2 we get actual time (Ta)= 6/2 ⇒ 3

      Therefore, the distance from person to the cliff (d) = 346 x 3 ⇒ 1038 m.

      The distance between the person and the cliff is 1038 meters.
