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 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 mostly 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 drop down from a higher energy level to a lower energy level, the atoms will give off yellow light instead of red light. Do you agree or disagree with either or both of the students? Explain your reasoning.
