    Answer:

    the wavelength of the first instrument is approximately 1.5 greater than that produced by the second instrument.

    Explanation:

    Given:

    f₁ = frequency = 266 Hz

    f₂ = 400 Hz

    Question: How do the wavelength of each of these sound waves compare, λ₁ = ?, λ₂ = ?

    The equation to solve this question is

    \lambda =\frac{v}{f}

    Here

    λ = wavelength of the sound

    v = speed of sound = 340 m/s

    f = frequency of each instrument

    You need to calculate both wavelengths

    \lambda _{1} =\frac{v}{f_{1} } =\frac{340}{266} =1.2782m

    \lambda _{2} =\frac{v}{f_{2} } =\frac{340}{400} =0.85m

    Ratio=\frac{\lambda _{1}}{\lambda _{2} } =\frac{1.2782}{0.85} =1.5038

    According to the results, the wavelength of the first instrument is approximately 1.5 greater than that produced by the second instrument.
