I got this question in a practice midterm and i can't seem to even start this problem, i tried using my textbook (university physics) and nothing to be found in there either.
Does anyone know start this problem?
thanks
so we were able to to get part a and b.
on part c we were able to get the time taken for light to travel in air but what would be the difference of the light traveling inside the fiber? does it slow down?
