Labels:text | screenshot | cartoon OCR: FLUORESCENT LAMP ELECTRODE GLASS TUBE ELECTRODE MERCURY VAPOR ATOM PHOSPHOR COATING T THE GLASS TUBE of a fluorescent lamp contains mercury vapor at low pressure. White phosphor coats the inside of the tube. When you switch on the lamp, electrodes at each end of the tube heat up and emit electrons. The electrons strike mercury atoms, causing them to emit ultraviolet light. When the phosphor atoms are hit by the invisible ultraviolet SEE ALSO rays, they emit white light. This conversion of one How Does It Work? kind of light into another is known as fluorescence.
