    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

    Remember that f is inversely proportional to lambda
