Since time perios is the time taken to complere one rarefaction and one compression:-
Now, time taken to complete 20 compressions and rarefactions:- 0.2 sec:-
time taken to complere one rarefaction and one compression = 0.2/20
= 0.01sec = time period
Since f=1/t
Therefore f= 1/0.01 = 100 hz
and labda = 2*50=100cm
