Return to Spectral Lines
Description:
Gas filled tubes are excited with a 5000v source. Diffraction lens glasses are passed out to the students (there are both full size diffraction glasses and 1/2 size, depending on audience size). Students are instructed to look at a line source such as a fluorescent light through the lens. Hold the lens so as to obtain the white light color spectra on both sides of the light source. Keeping this same orientation, students can observe the spectral lines obtained from the different gas tubes placed in the high voltage supply. Pictured in these photos is a fluorescent light, mercury, and helium tubes.
