Two light rays having the same wavelength ' $\lambda$ ' in vacuum are in phase initially. Then, the first ray travels a path ' $\mathrm{L}_1$ ' through a medium of refractive index ' $\mu_1$ ' while the second ray travels a path of length ' $L_2$ ' through a medium of refractive index ' $\mu_2$ '. The two waves are then combined to observe interference. The phase difference between the two waves is

A
$\frac{2 \pi}{\lambda}\left(\mu_1 L_1-\mu_2 L_2\right)$
B
$\frac{2 \pi}{\lambda}\left(L_2-L_1\right)$
C
$\frac{2 \pi}{\lambda}\left(\frac{\mathrm{~L}_1}{\mu_1}-\frac{\mathrm{L}_2}{\mu_2}\right)$
D
$\frac{2 \pi}{\lambda}\left(\mu_2 \mathrm{~L}_1-\mu_1 \mathrm{~L}_2\right)$
