Question

the velocity of sound in air is 360m/s while in water is 1440m/s . if the wavelength of sound in air is 2cm that in water is​

Answer 1

Answer:

velocity=frequency x wavelength

   360=frequency x 0.02

   frequency=360/0.02=18000 Hz (In air)

velocity=frequency x wavelength

 1440=18000 x wavelength

Therefore, wavelength in water=1440/18000=0.8 Hz
