Question

The-frequency-of-a-sound-wave-is-200Hz-and-its-wavelength-is-150cm-What-is-the-distance-travelled-by-a-sound-wave-in-the-time-taken-to-produce-150-waves

Answer 1

as frequency is 200 Hz that means 200 waves are produced in one second. So, time taken to produce 150 waves is 150/200 = 0.75 seconds.

velocity of wave = frequency*wavelength = 200*150 = 30000 cmps = 300 meters per second

so distance is 300*0.75 = 225 meters

Answer 2

hope u can understand
