According to the derivation of acceptance angle the first step is,
The condition for Total Internal reflection(TIR) is sin(i)≥n2/n1,
where i is angle of incidence in the core,
n2= refractive index of the cladding and n1=refractive index of the core.
sin(i(c))=n2/n1, where i(c) is the...
One of stokes relation is that r=r'. What does this mean exactly?
Is the phase difference between incident beam and reflected beam on a boundary between 2 mediums of different refractive indices ∏??
