2) State the condition so that internal reflection occurs in the above diagram.
The figure shows a ray of light falling normally on the face AB of an equilateral glass prism having refractive index`3/2`, placed in water of refractive index `4/3`.Will this ray suffer total internal reflection on striking the face AC? Justify your answer.
Total internal reflection occurs only when a ray of light passes from a ______ medium to a ______ medium.
