A chart showing the electromagnetic spectrum in wavelength, and the objects that are of similar size at each wavelengths. Gamma-rays wavelengths are about the size of atomic nuclei, X-ray wavelengths the size of atoms, UV wavelengths are the size of molecules, visible wavelengths like protozoans, infrared wavelengths like pinheads, microwaves like honeybees. Radio waves range from the size of people to buildings.
