| electromagnetic w.’s |
the spectrum of waves propagated through space or matter by the oscillation of an electric field and a magnetic field at right angles to one another; the waves travel perpendicularly to both the electric and magnetic fields, having a velocity in a vacuum of 3 × 108 m/s. They include, in order of decreasing wavelength, radio waves; microwaves; infrared, visible, and ultraviolet light; x-rays; gamma rays; and cosmic rays.
