 10 labs - bulkNow your students can see the absorption lines in the sun's spectrum, the spectra of energized elements in gaseous states and the double yellow line of mercury vapor in the spectrum of a fluorescent lamp. Light pollution can be studied by checking yellow street lights to see if they are high- or low-pressure sodium lamps. The spectrometer comes with a strip of film and a scale from which a color may be identified by wavelength in nanometers or photon energy in electron volts. The activities include: observing what diffraction grating does, calibrating the spectrometer and identifying various light sources and spectra of gaseous elements.Our Price: $66.00 |
