Two monochromatic

Given: -

The refractive indices of the material of the prism

For ray 1, = 1.35,

For ray 2, = 1.45,

Observations: -

For Ray 1,

TIR is not occurring as,

So the ray will get transmitted through the face AC as shown in the diagram

For Ray 2,

TIR is occurring as,

So, the ray will be reflected inside and will escape through the face BC
