Two light waves having the same wavelength $\lambda$ in vacuum are in phase initially. Then the first wave travels a path $L _{1}$ through a medium of refractive index $n_{1}$ while the second wave travels a path of length $L_{2}$ through a medium of refractive index $n _{2}$. After this the phase difference between the two waves is:
