Question

given give given that sound travel in air at 340 metre per second find the wavelength of the wave in air produced by a 20Khz sound source. if the same source is put in a water tank, what would be the wavelength of the sound waves in water? speed of sound in water =1480m/s

Answer 1

wavelength=u/v
20000/340=Answer

in second case
wavelength=u/v
20000/1480=Answer
