Consider the following discussion between the two students about the atoms and light coming from the red "OPEN" sign from the previous question and the light coming from a yellow "OPEN" sign they see across the street. Student 1: I think that all you need to do to get signs to give off light of different colors is to use tinted glass of different colors. If you electrify a gas, white light is emitted so the color of the glass gives the sign its color. Student 2: That can't be it because the electrons will always move between the same energy levels for atoms in a neon sign and so they will only give off red light. I think the yellow sign is filled with a different type of atoms with energy levels that are farther apart so when the electrons move from one level to another the atoms give off yellow light instead of red light.
