Abstract
A new, simple, inexpensive spectroscope for classroom experiments, a DVD spectroscope, is described and some emission spectra observed with the spectroscope are presented. This spectroscope is made with a sheet of cardboard, or an empty box, and a digital versatile disk (DVD). The quality of the spectra is much improved compared to that obtained by compact disk (CD) spectroscopes and DVD spectroscopes reported earlier. The resolution of this spectroscope is high enough to distinctly resolve the two yellow spectral lines of mercury at 577 and 579 nm. One can also observe clearly many Fraunhofer lines in the sunlight spectrum. Photographs of spectra are easily taken with a digital camera. Such images can be displayed on a monitor in real time, which helps students understand what is observed in the spectroscope.
