Photoacoustic effect a rotating slotted wheel. He noticed that the resulting acoustic signal was dependent on the type of the material and correctly reasoned that the effect was caused by the absorbed light energy, which subsequently heats the sample. Later Bell showed that materials exposed to the non-visible (ultra-violet and infra-red) portions of the solar spectrum can also produce sounds and invented a device, which he called "spectrophone", to apply this effect for spectral identification of materials. Bell himself and later John Tyndall and Wilhelm Röntgen extended these experiments, demonstrating the same effect in liquids and gases. However, the results were too
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".
