Electromagnetic Radiation and RHESSI

The links below provide sufficient background about this topic. One thing to keep in mind is that, in the various RHESSI websites, the sensitivity range of the RHESSI imager and spectrograph are usually given in electron volts (3 keV X-rays to 20 MeV Gamma-rays), while, in K-12 education, it is customary to teach about the wavelength, or the frequency of electromagnetic waves. Here are links to a convenient table and a chart which have electromagnetic waves by frequency, wavelength and electron volts.
