Solution

Given,
Number of vibrations in 3 seconds=1500
(i) Number of vibrations in 1 second=1500 / 3=500
So, frequency=500Hz
(ii)wavelength =2Distance covered by a compression and an adjacent rarefaction
=268
=136 cm
=1.36m
(iii) Velocity of sound wave=v
=frequency x wavelength
=500 x 1.36
= 680 m/s
