These handy and sturdy single-sided 8.5" x 5.5" cards include a detailed visual reference on the entire electromagnetic spectrum (from Gamma rays to radio waves) and an enlarged visual spectrum with such detail as wavelengths, frequencies, and energies.
You can also quickly discover the typical sources of each of the waves, if they are ionizing or non-ionizing, the size of their wavelength, etc. Also included are physics formulas that will let you easily convert wavelength to frequency and photon energy.
Whether you're a teacher, a student, or an aspiring physicist, these cards are invaluable!
