Abstract

A method is presented for displaying images and graphs of spectra on a single screen in the classroom. This demonstration can be used in discussions of atomic line spectra, absorbance spectroscopy, and solid-state bonding. The simultaneous display of both forms of the spectra helps students to make connections between the qualitative, visual spectra and quantitative, graphical representations.

  A new type of DVD spectroscope, the periscope type, is described and the numerical analysis of the observed emission and absorption spectra is demonstrated. A small and thin mirror is put inside and an eighth part of a DVD is used as a grating. Using this ...
