For the last installment in a five-part series on great music venues, Rolling Stone polled 26 insiders and musicians â from top managers to Miranda Lambert â and came up with a list of the nation's coolest arenas and stadiums.
The electromagnetic spectrum is a map of all the types of light that we can identify. It separates all the types of light by wavelength because that directly relates to how energetic the wave is. More energetic waves have shorter wavelengths while less energetic waves have longer wavelengths.
White light is dispersed by a prism into the colors of the visible spectrum. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430â770 THz.
