X rays are electromagnetic radiation with wavelength ranging from 0.1 - 1 Å.
X rays travel in straight lines.
X rays are produced when high energy electrons are stopped by metal barriers.
X rays are absorbed more readily by heavy elements than light elements.
X rays affect photographic plates.
X rays cause fluorescence.
X rays are not affected by electric or magnetic fields.
X ray Spectrum consists of line spectrum superimposed on a continuous spectrum.
X rays interact with materials and cause ionization.
X rays are diffracted by atomic or molecular arrangement in crystals.
