Total internal reflection can take place only, if |
the refractive indices of the two media are equal. light goes from an optically denser medium to a rarer medium light goes from an optically rarer medium to an optically denser medium The angle of incidence is less than the critical angle. |
light goes from an optically denser medium to a rarer medium |
The correct answer is Option (2) → light goes from an optically denser medium to a rarer medium $\text{Total internal reflection occurs when:}$ $\text{(i) Light travels from denser to rarer medium}$ $\text{(ii) Angle of incidence} > \text{critical angle}$ The correct option is: light goes from an optically denser medium to a rarer medium. |
