The spectrum of each element is specific because each element has certain quantized electron energy levels. When high energy electrons move through the gas the electrons of the atoms of the gas gain energy, move up an energy level and then quickly drop back down releasing a photo of a certain energy and wavelength. By using the equation l = dx/L and measured values for x and L we determined the spacing for our diffraction grating to be 1.60 x 10-6 meters. We set up a high potential difference between the ends of the tube and observed the spectrum produced by the tube through a diffraction grating. By measuring the distance between the central maximum and the first order image of purple (.163 m), green (.183 m), and red (.259 m) and using the equation l = dx/L we determined the wavelengths of the colors were able to use a spectrum chart to determine that the element inside the tube was hydrogen.
