Use spectroscope

Dim sources will produce better spectra if you can view them in the dark, so try turning other lights out or looking at outdoor lights after sunset.

If you are drawing spectra, draw at least three using the following blanks. Colored ink or pencil is better, but if you must use black and white, label each colored line. If you are photographing your spectra, you do not have to draw in these blanks unless you want to!!
