How does the fringe width of interference fringes change, when the whole apparatus of Young's experiment is kept in a liquid of refractive index 1.3?

When light enters a denser medium, its wavelength decreases by a factor 1.3 and hence the fringe width also decreases by a factor 1.3.

The fringe width will decrease.
