Given:
Frequency=n=512Hz
Veocity=V=340m/s
Velocity=frequency x Wavelength
wavelength=velocity/frequency
=340/512
=85/128m or 0.66m
Case 2:
frequency=n=256Hz
velocity=256 x 85/128=170 m/s
Frequency=n=512Hz
Veocity=V=340m/s
Velocity=frequency x Wavelength
wavelength=velocity/frequency
=340/512
=85/128m or 0.66m
Case 2:
frequency=n=256Hz
velocity=256 x 85/128=170 m/s

Velocity = frequency x wavelength
If frequency is halved
Velocity is also halved then the v will be equal to 340/2
= 170 m/s
