The element xenon is used in lamps that produce
intense, extremely short flashes of light, such as stroboscopes
and lights for high-speed photography. When a charge of electricity
is passed through the gas at low pressure, it emits a flash of
bluish-white light; at higher pressures white light resembling
daylight is emitted. Xenon flash lamps are used to activate ruby
lasers.
