Spectra (CD Spectroscope)

Type of activity: demo

Activity code: N-009

Description:

Observe the spectral lines of various gases using gratings on a CD / DVD. Please note some of the discharge tubes take a few minutes to warm up. A spectroscope can be used instead for small groups and for experiments requiring more detailed observations. In this case, point spectroscope at the source and adjust the slit size with its end-piece. Please note scale adjustments and focus are near the eye-piece.
