" Relation b/n refractive index of denser medium and critical angle is "
A sept index fibre has a relavitive refractive index of 0.88% . What is the critical angle at the core-cladding interface?
State the relation between the refractive index and the critical angle. Derive with suitable diagram.
(i) What is the relation between critical angle and refractive index of a material ? (ii) Does critical angle depend on the color of light ? Explain.
