This whole process has been really irritating and a complete waste of my time. I originally posted this question on the Classical Physics Forum, but someone moved it to here. If there was never any intention of answering the problem then why didn't someone say in the first place. I'm not...

You get n1(sinr cosd + cos r sind) = n2 sinr but how do I solve it when there's an r on both sides? And unless you're actually going to show me how to solve it then please don't bother posting!

BruceW wrote: "so from there it is straightforward to solve for r. " That may be so for some, but for this ageing dunce it isn't! So if someone would be kind enough to help me out and show me how to solve it I'd be very appreciative.

You mean sin(A+B) = sin(A)cos(B)+cos(A)sin(B) ? Can you help out further because my maths still isn't good enough to solve it. Thanks

Hi, Can someone tell me how to find the incident and refractive angles when only the deviation angle is known? For instance, I know that Snells law is n1 sin(i) = n2 sin(r) I know that the materials are air (n1=1) and glass (n2=1.5) And I know that the deviation angle d is 30deg. I can...
