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.
When electromagnetic radiation is spread out according to itswavelength, the result is a spectrum, as seen in Fig. 1. The visible spectrum, as seen in arainbow, is only a small part of the whole electromagnetic spectrum. The electromagneticspectrum is divided into five major types of radiation. As shown in Fig. 1, these includeradio waves (including microwaves), light (including ultraviolet, visible, and infrared), heatradiation, X-rays, gamma rays, and cosmic rays. Your eye can detect only part of the light INTRODUCTION The Electromagnetic Spectrum Fig. 1.
