here is the receipt.
the claim

Frequency equals wave speed divided by wavelength.

Recorded sources
2 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that frequency equals wave speed divided by wavelength?

Yes. A reference article on frequency states that the frequency of a sinusoidal wave equals the phase velocity divided by the wavelength, and a second source gives the equivalent relation that wave speed equals frequency times wavelength.
