That's it!

That equation that shows the relationship between the speed, frequency and wavelength of a wave is what we know as the wave equation.

Symbolically,

v = fλ

where,

v = speed (ms⁻¹)

f = frequency (Hz) and

λ = wavelength (m).

λ is Greek letter lambda.

A mnemonic I use for this is

v = fλ (vee is equal to fela) :D

In certain cases however, a more complex form,

y = A sin [(2πx/λ) - ωt] may be used.

Even more complex forms, involving differential calculus, exist; yet, all a wave equation does is to describe the passage of harmonic waves through a medium.

Was I clear enough?

And I have told you what a wave equation is
