In our studies of light so far, we have review the basic ideas of light transmission, including the ray and wave models (link to a prior post on this topic here. READ IT!), and the ways light traveling as a wave can create interference patterns, and the amazing interactions of diffraction (link to a prior post here. READ IT NOW!).
You need to understand how diffraction works, and to help you with your preparation for your outcome, here is a simulation that will help you explore diffraction phenomena – you must take your time to explore how the factors of wavelength (colour), slit width, slit separation and distance from screen interact to affect “fringe width” – the distance between maxima on the projection screen. You may wish to use your explorations in the simulation to augment and clarify your notes on your summary pages. Remember that you may not include general points of theory or examples unconnected to the context provided on those sheets (Pages from Outcome.)
