Doppler effect - Observed frequencies

So the doppler effect is the apparent change in frequency or wavelength.

The one in the book is to do with wavelengths:

(Observed - emitted) / Emitted = Velocity / Speed of light

How does it change for frequency?

V= f * lambda

f = v/ lambda?

Im a bit stuck, any help is appreciated :smile:

Remember that f is inversely proportional to lambda
