The sum of number of compressions and rarefactions produced by a sound wave per second is 200. The frequency of sound wave is
The correct option is C 100
Frequency is measured as the number of wave cycles that occur in one second. The unit of frequency measurement is Hertz.
Sum of compressions and rarefactions = 200
Thus number of cycles = 100
(one compression and rarefaction make a cycle)
Thus frequency = 100 Hz
