Answer:

We know that  20 compressions and 20 rarefactions make   20 oscillation

of the wave so the time period is 0.2/20=0.01 s

so  frequency is  f=1/T

1/0.01=100 Hz 

distance between rarefaction and compression is 50 cm so  distance between two rarefactions and two compressions is 2*50=100 cm=1 m........
