Hi! Need ideas for case study about electromagnetic waves I've been having trouble of finding a case study for electromagnetic waves. Can you please give me neat ideas? I'm having interest on lasers now so I would want to focus on monochromatic lights but can't think of a new problem to be newly solved and my other problem is that it should not be deeply relate (my case study) to quantum physics although i still can; in other words i want to relate laser case study in terms of electromagnetic waves. haven't had any reading sessions in physics yet so i still dont know this stuff, im very busy working on maths. my professor said we have to give the case study title this friday. need help. any suggestions will do (about e-mag waves) thanks so much.
