Open the Emission version of the Gas Lamp Spectroscopy computer program and place the unkown gas lamp socket.
When the unknown is in the socket, you can create your own spectrum by dragging the lines near the top of the screen. Drag the computer-generated spectral lines so that the spectrum is similar to the one you observed for an LED.
Create an energy level diagram for an atom that could produce this spectrum.
Compare your results with other students who were assigned different LEDs. The resulting discussion should focus on answering the following questions.
