Finding good answers to the questions that are related to the physics of light and optics is not easy because these are mostly related to graphic experiments or multimedia experiments. Still, there are also verbal explanations that must be provided. When you need light and optics physics help, start with the verbal aspect of light and optics because if you cannot provide a solution in your own words, the graphs and lab experiments will not help you much. Once you get the text part, continue with the equations and the outcome of your research to get your paper structure accurate.
