Relativistic Doppler effect invisible ultraviolet wavelengths, infrared light is blueshifted into the visible range. Precisely what changes in the colors one sees depends on the physiology of the human eye and on the spectral characteristics of the light sources being observed. The Doppler effect (with arbitrary direction) also modifies the perceived source intensity: this can be expressed concisely by the fact that source strength divided by the cube of the frequency is a Lorentz invariant This implies that the total radiant intensity (summing over all frequencies) is multiplied by the fourth power of the Doppler factor for frequency. As a consequence, since Planck's
Ultraviolet (Light My Way) school when it came out and we'd drive around in my friend's mom's car and rock that shit all the time. When we were asked to record a cover, 'Ultraviolet' was a unanimous choice. It's reassuring to know that we're still on the same page after all these years. We brought it back to its bare bones, dumbed it down a little, took it back to the rock song underneath." The beginning of the song was also sampled by Enigma in their 1994 song "The Eyes of Truth".
