Objectives Students will Compare different spectrums given off by various light sources around them. To print out the Student Copy only, click here . Any other light sources available Check with your school engineer about what different light sources are available in your school. Most gyms have mercury vapor lights and some schools have sodium lights also.
Incandescent lights can be slide projectors or overheads.
Be careful to eliminate light sources contaminating each other. You may want to have only one light source on at a time and all students do that one and then turn it off and do another one. Make sure that you block all outside light from entering. Procedure Point the slit of the spectroscope toward the light source. Get the spectrum to line up with the scale in the scope.
