When a ray of light is incident at an angle $\theta=60^{\circ}$ on an air-glass interface, the reflected ray is 100 percent plane polarised. The value of the refractive index of the glass with respect to air $\left(a^{n} g\right)$ is given by: |
0.577 0.866 1.15 1.732 |
1.732 |
The correct answer is Option (4) → 1.732 |
