Ultraviolet lights are made using special lamps that contain a gas such as Mercury, which emits UV radiation when an electric current passes through it. The gas is enclosed in a tube made of quartz or special glass that allows the UV radiation to pass through. When the lamp is turned on, the electricity excites the gas atoms, causing them to release UV light.
