Question 29

A ray of light travels in medium A towards a horizontal boundary with medium B. Total internal reflection occurs at the boundary, where the angle of incidence is $θ\theta$ .

Which option correctly describes the angle $\theta\,$ and the refractive index of medium B relative to medium A?

$θ\theta$ is smaller than the critical angle; refractive index of medium B is greater than the refractive index of A

$θ\theta$ is smaller than the critical angle; refractive index of medium B is less than the refractive index of A

$θ\theta$ is greater than the critical angle; refractive index of medium B is greater than the refractive index of A

$θ\theta$ is greater than the critical angle; refractive index of medium B is less than the refractive index of A
