Q1

Two light waves having the same wavelength \(\lambda\) in vacuum are in phase initially. Then the first wave travels a path \( \mathrm{L}_1\) 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 :

a

\( \frac{2 \pi}{\lambda}\left(\frac{L_1}{n_1}-\frac{L_2}{n_2}\right) \)

b

\( \frac{2 \pi}{\lambda}\left(n_1 L_1-n_2 L_2\right) \)

c

\( \frac{2 \pi}{\lambda}\left(n_2 L_1-n_1 L_2\right) \)

d

\( \frac{2 \pi}{\lambda}\left(\frac{L_2}{n_1}-\frac{L_1}{n_2}\right)\)
