Consider six proposed properties of electromagnetic radiation: wave speeds of 3.00 x 10° km/s and 3.00 x 10°m/s, wavelengths
of 563 nm and 0.193 nm, and frequencies of 2.15 x 1018 Hz and 6.26 x 1014 Hz. Place these according to whether they apply
only to the X-ray band, only to the visible light band, to both bands, or to neither band.
