Relativistic Doppler Factor
f = f_0·sqrt((1 - β)/(1 + β))
What it says
The observed frequency from a source receding at a fraction of light speed.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
f | Observed frequency (Hz) | T^-1 |
f_0 | Emitted frequency (Hz) | T^-1 |
β | Speed as a fraction of c (dimensionless) | 1 |
