1. What are electromagnetic waves? What is electromagnetic radiation? 2. What do we suggest an electron, within an atom, does when the atom produces a certain color in the spectrum? 3. In terms of electrons what is a difference between atoms of one element and atoms of another element that produce spectra that are very different? Compare for example an atom with a complex emission spectrum and an atom with a spectrum having only a few lines in its spectrum. 4. Think about the energy of different wavelengths of light. If you had a light source that emitted the exact same quantity of light, but at different wavelengths, which color of light, red or blue, would have more energy
