Estimating the Wavelength of Sodium Emission in Flame--The Easy Way
Wahab, M. Farooq
Physics Teacher, v47 n6 p367-369 Sep 2009
Simple "box spectroscopes" are not new. Different methods of building them at home using cheap diffraction gratings have been described. However, their use has often been confined to looking at street lights, discharge tubes, and enjoying the beautiful spectra of various lamps. Construction of the box spectroscope usually involves a narrow slit made with metal plates or razor blades at one end and a transmission grating at the other end. The slit is directed toward a light source and the light spectrum is viewed through the grating. In the experiment described in this paper, a simple box spectroscope is used, along with a digital camera, for making quantitative wavelength measurements.
