1. The problem statement, all variables and given/known data
I saw this question on this forum
Can anyone tell me where my maths has gone wrong?
3. The attempt at a solution
I've tried to calculate the maximum possible path difference along a fibre of length l and width d that has a maximim transmission angle of to the normal of the core cladding boundary [tex]\theta[/tex]. I've come up with an expression for this path difference in terms of the length of the fibre... <Attached are my scribbles> (L is the longest path and [tex]\Delta[/tex]L is the greatest possible path difference.)
The problem with this is that the maximum path difference is independant of the width of the fibre and depends only on the angle..
