| electromagnetic wave |
an electric field spreading in wavelike-fashion through space at a speed of about 300 000 km.sec, with its direction and intensity at any point in space oscillating rapidly back and forth. James Clerk's Maxwell's theory in 1864 suggested that light was such a wave, and today we know that such waves include all forms of light--also infra-red and ultra-violet, as well as radio waves, microwaves, x-rays and gamma rays.
