Hi All... Who knows the formula of the Dopler´s Effect??Please someone help me.This is a little curiosity that I Have.Regards.

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!
