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,
Primetime Emmy Award for Outstanding Art Direction for a Miniseries or Movie Direction for a Miniseries or Movie Primetime Emmy Award for Outstanding Art Direction for a Miniseries or Movie The Primetime Emmy Award for Outstanding Art Direction for a Miniseries or Movie is a retired award that was handed out annually at the Creative Arts Emmy Awards. In 2014, the category was restructured into Outstanding Production Design for a Narrative Contemporary or Fantasy Program (One Hour or More) and Outstanding Production Design for a Narrative Period Program (One Hour or More).
