# A source of sound produces 20 compressions and 20 rarefactions in 0.2 seconds. The distance between a compression and the next rarefaction is 50cm. find the wavelength, frequency, timeperiod.

The Brainliest Answer!

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
