v =344m/s (given)
wavelength =0.86m
therefore
frequency= v/wavelength =
=344/0.86
=400 hertz
Since the frequency remains same so,
velocity = frequency × wavelength
= 400 × 0.8
= 500 m/ s
wavelength =0.86m
therefore
frequency= v/wavelength =
=344/0.86
=400 hertz
Since the frequency remains same so,
velocity = frequency × wavelength
= 400 × 0.8
= 500 m/ s
