Question

Total internal reflection occurs when light travel from :

• A. A rarer medium to a denser medium and the angle of incidence is less than the critical angle
• B. A denser medium to a rarer medium and the angle of incidence is less than the critical angle
• C. A rarer medium to a denser medium and the angle of incidence is greater than the critical angle
• D. A denser medium to a rarer medium and the angle of incidence is greater than the critical angle

Answer 1

The correct option is D A denser medium to a rarer medium and the angle of incidence is greater than the critical angle

Total Internal Reflection takes place when light travels from denser to rarer and also the angle of incidence should be greater than critical angle.
