Question

Sound wave of wavelength 15cm travelling with velocity 300m/s in a medium enter into another medium in which its velocity is 1800m/s and wavelength is

Answer 1

Answer  

here frequency is same in both cases hence we can equate both cases

300/15=1800/x-------------(frequency =velocity/wavelength)

x=wavelength of the second medium=90 cm
