Speed = Frequency x Wavelength
that shows the relationship between the speed, frequency and wavelength
of a wave is what we know as the wave equation.
v = fλ
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.
more complex forms, involving differential calculus, exist; yet, all a
wave equation does is to describe the passage of harmonic waves through a
Was I clear enough?
