1. Answer:

   Wavelength of sound wave = 1 m

   Explanation:

   Given

   speed of sound wave = 340 m[tex]s^{-1}[/tex]

   frequency of sound wave = 340 Hz = 340 [tex]s^{-1}[/tex]

   wavelength of sound wave = ?

   We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

   v = fλ

   Hence wavelength of sound wave λ = v/f

                                                                =  340 m[tex]s^{-1}[/tex] / 340 [tex]s^{-1}[/tex]

                                                                = 1 m
