Ultraviolet divergence short distances. The name comes from the earliest example of such a divergence, the "ultraviolet catastrophe" first encountered in understanding blackbody radiation. According to classical physics at the end of the nineteenth century, the quantity of radiation in the form of light released at any specific wavelength should increase with decreasing wavelength—in particular, there should be considerably more ultraviolet light released from a blackbody radiator than infrared light. Measurements showed the opposite, with maximal energy released at intermediate wavelengths, suggesting a failure of classical mechanics. This problem eventually led to the development of quantum mechanics. The successful resolution of the
Ultraviolet (Light My Way) as such: "I'd go in and say, 'The song has gone, whatever it is you liked about this song is not there anymore. Sometimes, for example, the song would have disappeared under layers of overdubs." "Ultraviolet (Light My Way)" is written in a 4/4 time signature. The lyrics of "Ultraviolet (Light My Way)" are addressed to a lover, and imply that their relationship is threatened by some sort of personal or spiritual crisis, coupled with a sense of unease over obligations. Indeed, lead vocalist Bono has called the song "a little disturbed". The song opens with 45 seconds of soft
