JEE Advanced Model Paper 13 with solutions for online practice

A parallel beam of mono chromatic light is incident on the two slits of YDSE andthe interference is observed on a screen. The space between slits and screen isfilled with a liquid of refractive index µ0 . Two transparent slabs of thicknesses t1 and t2 and refractive indices 2µ0 and 3µ0 are introduced in front of slits as shownand central maximum is formed at screen centre C. Now the liquid is removed andthen the central maximum will be shifted. Based on this, choose the correctstatement(s)
