just gonna bump this bad boy up there because i feel that everyone will benefit from knowing this answer!!!!!
wtf is this ****?

I was gonna say use n lander = d sin theta

but idk.

indeed, they had the audacity to throw this in an AS paper. the worlds largest UK exam board are the perpetrators - the assy qualification Alliance (AQA)
Im assuming it goes from 1 at A to 1.5 stays at 1.5 for C then goes back down to 1?

Quick guess.

aqa stepping up their game damn, and I thought they were the easiest exam board.
Seems simple enough to me. The thing that seems to be missing is the refractive index of the cladding but that must surely be included in part A. If you don't get it, just find the mark scheme.

i promise you brother i would not lie to you, they haven't given me any sort of index for the clads.

if its so simple ( which it may be ) could you please propose a solution?

thank you ever so much

calm down guys. It's all cool. check the link above you lot. AQA is a joke of an exam board honestly. I've got A2 physics exams couple weeks from now and i haven't revised for sh1t. got 100% ums for AS in case u were wondering

Do you have the solutions? It was a legit guess, that I think could be right, but I'm really not sure.

Edit: and seeing as I misread the glasses refractive index for cladding I'm definately wrong.

Maybe you can reverse calculate the cladding index from the critical angle?

The question is really easy if you engage your brain and read it properly. All the information is written down for you.

How is anything hard when you know what to do?
