Last updated: 6/13/2023

Monochromatic light is incident on a plane interface AB between two media of refractive indices and H2 2 at an angle as shown in figure The angle is infinitesimally greater than the critical angle two media so that total internal reflection takes place Now if a transparent slab DEFG of uniform thickness a having refractive index 3 is introduced on the interface as shown in the figure Which of the following statements are correct D G Medium I Medium III 3 E F B Medium II If 3 total internal reflection will take place at face GF If 3 1 light will refract into the slab
