Total internal reflection can take place only when light passes from:
- aa rarer to a denser medium
- ba denser to a rarer medium
- cany medium to any other
- dvacuum into glass
Original Khojo Papers practice question — not from a past board paper.
Answer
a denser to a rarer medium
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Only then does the refracted ray bend away from the normal and reach 90° at the critical angle.
