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,
AACTA Award for Best Direction in a Television Light Entertainment or Reality Series AACTA Award for Best Direction in a Television Light Entertainment or Reality Series The AACTA Award for Best Direction in a Television Light Entertainment or Reality Series is an accolade given by the Australian Academy of Cinema and Television Arts (AACTA), a non-profit organisation whose aim is to "identify, award, promote and celebrate Australia's greatest achievements in film and television." The award is handed out at the annual AACTA Awards, which rewards achievements in feature film, television, documentaries and short films. Previously, direction for light entertainment and reality series were recognised in the Best Direction in Television category. However, when
