Cherenkov radiation permeability and formula_16 is the index of refraction of the material the charge particle moves through. Unlike fluorescence or emission spectra that have characteristic spectral peaks, Cherenkov radiation is continuous. Around the visible spectrum, the relative intensity per unit frequency is approximately proportional to the frequency. That is, higher frequencies (shorter wavelengths) are more intense in Cherenkov radiation. This is why visible Cherenkov radiation is observed to be brilliant blue. In fact, most Cherenkov radiation is in the ultraviolet spectrum—it is only with sufficiently accelerated charges that it even becomes visible; the sensitivity of the human eye peaks at green,
A Moving Sound of the human condition." A Moving Sound has attracted international attention for opening doors to the under explored territory of Far Eastern music. The group is intensely passionate about how it presents the use of traditional instruments in its contemporary sound. Their approach is to be holistic – combining art, spirituality, social awareness, and a universal love of humanity play key roles in the creative process. According to Tom Pryor, music supervisor for National Geographic, "A Moving Sound is one of the most original outfits working in the world music arena today, an inspired marriage of Taiwanese traditional sounds and
