NettetHold the tube upright and point the top slit at a fluorescent light. Press your eye to the viewing hole. On the CD, look for a clear, solid line of light broken up into colored bands: this is the spectrum of light reflected from fluorescent light onto the CD. NettetLine spectrum of mercury vapor. The blue-green tint of mercury vapor lamps is caused by the strong violet and green lines. In low-pressure mercury-vapor lamps only the lines at 184 nm and 254 nm are present. Fused silica is used in the manufacturing to keep the 184 nm light from being absorbed.
