The velocity  of a  longitudinal  sound wave  in an ideal  gas is given  by    where   is γ   the ratio of  the specific  heat at  constant  pressure to  that at  constant  volume, P is  the pressure,  and   is the ρ   mass  density.  Assuming an  ideal gas  with    and   at  standard  temperature  and  pressure,  find the  wavelength  for a    sound wave.
