Answer:
Explanation:
The equation for this is
[tex]f=\frac{v}{\lambda}[/tex] where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
[tex]256=\frac{350}{\lambda}[/tex] and
[tex]\lambda=\frac{350}{256}[/tex] which means that
the wavelength is 1.37 m, rounded to the correct number of significant digits.
