The refractive index of the medium with a certain region x 0

Last updated: 6/11/2023

The refractive index of the medium with a certain region x 0 y 0 changes with y A thin light ray travelling in the x direction in medium having refractive index 1 strikes another medium of refractive index u at right angles and moves through the medium along a circular arc of radius R as shown in the figure The material with the greatest known refractive index is diamond but even the refractive index of this material does not reach the value Hmax 2 5 It is this limit that sets the maximum angular size of the are the light ray can cover Angular size of are is the angle subtended by the arc at the centre 3
