Unformatted text preview: intensity of the light. 2. The reason for hydrogen having four colours on the spectrum is because when the electron in the hydrogen atom moves away and towards the nucleus it produces a new colour represented on the spectrum. 3. The light emitted by Hydrogen is different from the light emitted by other elements because of number of electrons in each element. The more electrons an element there is more movement of electrons when it is excited. Therefore since there is more movement of electrons we know that when electrons move from their orbitals it gives off a certain colour. 4. Gas discharge tubes and street lights are similar because they both contain a certain gas inside an enclosed tube. They also share another similarity which is they both excite electrons in order to kick start the production of light. Some of the gasses used in street lights are sodium which is heated up until is becomes a gas, mercury, carbon,...
