The speed of the sound wave after the flash was seen, in the experiment for measuring the speed of sound gun is 110 m/s.

Speed of the sound wave

The speed of the sound wave can be determined by applying the principle of echoe as shown below;

v = 2d/t

where;

  • d is the distance of the sound wave
  • t is time of motion

v = (2 x 715) / (13)

v = 110 m/s

Thus, the speed of the sound wave after the flash was seen, in the experiment for measuring the speed of sound gun is 110 m/s.
