Answer:
I am giving example of 60 compression and 60 rarefraction
Explanation:
Frequency of wave is defined as the number of waves produced in 1 second. A longitudinal wave is formed by one compression and one rarefaction , we have 60 compressions and 60 rarefactions in 0.6s i.e. 60 waves produced in 0.6s ,
in 0.6s the number of wave produced =60
in 1s the number of wave produced =60/0.6=100Hz ,
therefore , frequency f=100Hz
