Electromagnetic Spectrum Chart
|
Our chart shows the different frequencies and wavelengths of electromagnetic waves that you confront on a daily basis. It describes these waves through a series of arc-shaped bands which advance from the center of the chart. It also has three bands describing how the wavelengths are made and their general and specific names. Other information includes: radio and microwave usage; black body curves; emission spectra; atmospheric absorption bands; and x-ray and gamma ray absorption. The chart comes with an instruction sheet that contains background information and a chart key. Size: 24 x 30.
