Doppler Blueshift

Doppler blueshift is caused by movement of a source toward the observer. The term applies to any decrease in wavelength and increase in frequency caused by relative motion, even outside the visible spectrum.

The blueshift equals the velocity divided by the speed of light in a vacuum.

Formula

QuantityVariable["z", "Unitless"] == Quantity[-1, "SpeedOfLight"^(-1)]*QuantityVariable["v", "Speed"]

symbol description physical quantity
z blueshift "Unitless"
v velocity "Speed"
