Spectrum tube are valuable tools for both scientific research and education, as they provide insights into the atomic and molecular properties of various gases. By studying the light emitted from these tubes, scientists gain a deeper understanding of the fundamental processes occurring within atoms, making them an essential piece of laboratory equipment. A spectrum tube consists of a sealed glass tube filled with a gas at low pressure, and electrodes at each end. When an electric current passes through the gas, the atoms or molecules in the gas become excited, and as they return to their lower energy states, they emit light.
