Question

Which equations represent the relationship between wavelength and frequency for a sound wave? Check all that apply.

v = lambdaf
= vf
f = v
= StartFraction v over f EndFraction.
= StartFraction f over v EndFraction.
f = StartFraction v over f EndFraction.
f = StartFraction lambda over v EndFraction.

Answer 1

The correct relationships (equivalent forms) are:

- v = λ f
- λ = v / f (rearrangement)
- f = v / λ (rearrangement)

From your list those correspond to the line "v = lambdaf" and the line "= StartFraction v over f EndFraction." (the latter being λ = v/f). The other listed equations are not correct.
