Dear Y12
Sorry I am not in, have bronchitis, recovering and should be back to normal next week.
Work for today and tomorrow's lessons;
1. Young's double slit experiment - read about this in your textbooks and make notes including diagrams on what the experiment was, what his explanation was of the observations, why this was significant and what the equation is to describe this. Do the relevant questions from your textbook on this section.
2. Diffraction gratings - describe what these are, read the relevant part of your textbook and make notes, including the equation and what it means, how the pattern is formed,with a laelled diagram to show this, why the central maxima is brightest, and how to derive the equation. Do the relevant questions from your textbook on this section.
3. Plan an experiment to test the relationship given by both these equations using standard lab equipment - this is your next required practical which we will be doing next week.
Thanks and see you next week
Ms H
