Answer:

Wavelength of sound in meters = 1.348 m

Explanation:

Given

speed of sound = 34500 cm $s^{-1}$ = 345 m $s^{-1}$ (since 1 cm = 0.01m)

frequency of sound = 256 Hz = 256 $s^{-1}$

Wavelength of sound in meters = ?

We know that all waves have same relationship among speed s, frequency f and wavelength λ, which is given by the equation

v = fλ

Wavelength λ = v/f

= 345 m $s^{-1}$ / 256 $s^{-1}$

=1.348 m

Hence wavelength of sound in meters = 1.348 m
