In figure, a wavefront AB moving in air is incident on a plane glass surface xy. Its position CD after refraction through a glass slab is shown also along with normal drawn at A and D. The refractive index of glass with respect to air will be equal to
- \(\frac{\sin \theta}{\sin \theta^{\prime}}\)
- \(\frac{\mathrm{BD}}{\mathrm{AC}}\)
- \(\frac{\sin \phi}{\sin \phi^{\prime}}\)
- \(\frac{A B}{C D}\)
