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
• X-ray and gamma ray absorption
