|Reveal the hidden nature of color and visible light with this durably constructed, economical spectroscope. Begin investigating bright line spectra to unveil the atomic origin of light the instant you pick up this hand held spectroscope. Contrast the differences between gas discharge (fluorescent) and incandescent lights. Discover the workings of diffraction gratings and how they separate white light into its component colors. Measure the wavelengths of visible light from 4000 to 7000 Angstroms with the precision of +/- 50 Angstroms using the built in scale. Supplied with an excellent set of instructions that reviews the historical aspects of light theory, diffraction gratings, and provides suggestions for numerous experiments to help you unlock the world of visible light.|
