Question

A source of wave produces 40 crests and 40 troughs in 0.2 seconds. the distance between the crest next thought is 50 cm. find the 1.wavelength 2.frequency 3.time period of the wave

Answer 1

Wavelength=50 cm=0.5 m

Frequency=40/0.2

                 =200 Hz

Time period=1/Frequency

                   =1/200

                   =0.005 sec
