Question

The frequency produced by a tuning fork is 41.5

Hz. What is the distance travelled by sound when

the tuning fork makes 20 vibrations?

Answer 1

Given:

frequency produced by a tuning fork, v = 41.5 hz

time period of the fork = (1/41.5) sec now its mentioned that the tuning fork makes such 20 vibrations so total time of the event, t = (20/41.5) sec --------------------------(1)

Since

Speed of sound, s = 340 m/s -----------------(2)

Hence

Distance travelled = s × t meters
