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 A Moving Sound A Moving Sound () or Sheng Dong is a Taiwanese music act consisting of vocalist/dancer Mia Hsieh, vocalist, bass guitarist and zhong ruan player Scott Prairie, erhu player I-Fang Chen, and zhong ruan player Chih-Ling Chen. In A Moving Sound’s music traditional Taiwanese music forms are reinterpreted to create new original song compositions. Instruments such as the erhu (fiddle), the zhong ruan (lute), and the transcendent vocals and dance of lead singer Mia Hsieh, transport listeners on a journey that Global Rhythm magazine described as “...delicately balanced between many worlds…an entryway to Eastern music and artful expression
