    Answer:

    Frequency = 1,550Hz

    Explanation:

    To solve this we can use the equation: f=\frac{v}{\lambda}

    (frequency = velocity/wavelength).

    We are given the information that the wavelength is 22cm and the speed is 340m/s. The first step is to make sure everything is in the correct units (SI units), and to convert them if needed. The SI Units for velocity and wavelength are m/s and m respectively. This means we need to convert 22cm into meters, which we can do by dividing by 100, (as there are 100cm in a meter). 22/100 = 0.22m

    Now we can substitute these values into the formula and calculate to solve:

    f=\frac{340}{0.22} \\\\f=1545.454...

    Simplify to 3 significant figures:

    f = 1,550Hz

    (Which I believe is just below a G6 if you were interested)

    Hope this helped!
