In this problem it is given that the maximum audible frequency of bat   f  =      10          5        H  z and the speed of sound waves in air   v  =  343  m      s          −      1      .We are asked to calculate Wavelength of sound waves.By substituting the above given values in (1),  λ  =      343          10              5              λ  =  343  ∗      10          −      5        m  =  3.43  m  mResult:  λ  =  3.43  m  m

The maximum audible frequency (f) of bats is,  f  =  100  k  H  z  =  100  ×      10          3        H  z  =      10          5        H  z.The speed of sound waves in air is,  v  =  343  m  .      s          −      1      So the wavelength of the sound waves is given by  λ  =      v    f    =      343          10              5              =  343  ×      10          −      5        m  =  0.00343  m  =  3.43  m  mResult:3.43 mm
