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-sound Best Sound ). A-Sound put out their debut album in July 2008: Release. It was the first Mongolian rock album to feature some songs in English. The album featured many popular songs, including: "Uyanga," "Shine On," and "Forever." "Uyanga" is a popular girl's name and is a pleasant song sung in Mongolian. "Shine On" and "Forever" are two slices of immaculate pop song-craft, and to music critic (among other things) Brian Offenther, should have been international pop smashes. In "Forever," lead singer Temuulen's crystal clear voice really sours. In early 2009, a deluxe version of Release was put out and
