Question

Sound 1 Has frequency of 220 Hz. If the speed of sound is 330 m/s , what is the wavelength of sound 1

Answer 1

Answer:

Frequency=200Hz

Speed of sound =330m/s

Number of vibrations=20

therefore,Time period=

frequency

1

=

200

1

=0.005sec

Total time= Time period × number of vibrations

=0.005×20=0.1sec

Now,

Distance travelled= Speed × time

=330×0.1=33m
