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,
Not a Damn Thing Changed tribute to one of the guys I grew up with who hung himself in January. He was three months older than me and we walked through life together." A music video to accompany the release of "Not a Damn Thing Changed" was first released on YouTube on 11 October 2018 at a total length of three minutes and forty-nine seconds. The video was directed by René Sascha Johannsen. Forchhammer's real-life childhood friends appear in the video, which they filmed in Copenhagen and their hometown, Christiania. Not a Damn Thing Changed "Not a Damn Thing Changed" is a song by Danish
