In the adjoining diagram, 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 the normals drawn at $A$ and $D$. The refractive index of glass with respect to air ($\mu = 1$) will be equal to

The figure shows a surface $XY$ separating two transparent media, medium - $1$ and medium- $2$. The lines $ab$ and $cd$ represent wavefronts of a light wave traveling in medium- $1$ and incident on $XY$. The lines $ef$ and $gh$ represent wavefronts of the light wave in medium- $2$ after refraction.
The phases of the light wave at $c, d, e$ and $f$ are $\phi_c,\phi_d, \phi_e$ and $\phi_f$ respectively. It is given that $\phi_c \neq \phi_f.$
