A bat flying in a cave emits a sound and receives its echo 0.1s later. Show that the distance to the wall of the cave is 17m.


  • Conceptual Physical Science -

    distance = rate x time
    speed of sound is 340 m/s (see your later question)
    d = 340 x 0.1 = 34 meters.
    BUT the sound must travel to the wall of the cave AND back so that makes it 17 m to the wall and 17 m back to the bat.
