According to given conditions TIR must take place at both the surfaces A B and A C. Hence only option (a) is correct.

Q. The refractive index of a material of a prism of angles $4 5^{\circ} - 4 5^{\circ} - 9 0^{\circ}$ is $1.5$ . The path of the ray of light incident normally on the hypotenuse side is shown in

According to given conditions TIR must take place at both the surfaces $A B$ and $A C$ . Hence only option $(a)$ is correct.

Q. The refractive index of a material of a prism of angles 45∘−45∘−90∘ is 1.5. The path of the ray of light incident normally on the hypotenuse side is shown in

According to given conditions TIR must take place at both the surfaces AB and AC. Hence only option (a) is correct.
