Question

a source of wave vibrates with a frequency of 500 hz.the wave travels 33m in 0.1 seconds.how far does the wave travel when the source execute 150 vibration Ans:99m. ......please explain this!

Answer 1

First,
Wavelength = velocity / frequency
Velocity =330 m/s
Frequency = 500 hz
So wavelength =33/50

Distance travelled =velocity / frequency * no. of oscillations

HENCE,
Distance travelled = 33/50*150
=33*3
=99 m
