    DOPPLER EFFECT FOR MOVING OBSERVER:

    F = (1+ OR 1-(U/V))f

    Units are inversed seconds

    v = speed of wave
    u = speed of observer
    F = with doppler effect
    f = without doppler effect

    I just got this outta my old physics book as we didn't cover this chapter so it's as new to me as to you!!!

    DOPPLER EFFECT FOR MOVING SOURCE:

    F = ((1)/(1+ or 1-(U/V)))f

    Same units as above
    Same variable definitions as above



    DOPPLER EFFECT FOR MOVING SOURCE AND MOVING OBSERVER

    F = ((1+ or 1-(u/v))/(1+ or 1-(U/V)))f

    Same units as above
    Addition variables:

    u = moving observer
    U = moving source

    Relativistic transformation given by [squ](1 + v/c) / [squ](1 - v/c) if you want that one for high velocities.

    Wavelength is red-shifted (lengthened), and frequency shortened for sources moving away. Blue-shift/longer frequency for sources moving towards observer.

    Yeah mulder. Interesting I didn't see these relativistic equations in the relativity chapter....

    The low note on a bass guitar, traveling at the speed of light, ouch that might hurt my ears!!!!!!
