a very highly exhausted vacuum tube by an electrical
discharge; now more commonly called X-ray. It is
composed of electromagnetic radiation of wavelength
shorter than that of ultraviolet light but longer than
that of gamma rays. It is capable of passing through many
bodies opaque to light, and producing photographic and
fluorescent effects by which means pictures showing the
internal structure of opaque objects are made, called
X-rays, radiographs, sciagraphs, X-ray photographs,
radiograms. So called from the discoverer, W. C.
R["o]ntgen.
X ray, the R["o]ntgen ray; -- so called by its discoverer
because of its enigmatical character, x being an algebraic
symbol for an unknown quantity.
