Assertion: if a glass slab is placed in front of one of the slits, then fringe with will decreases.
Reason: Glass slab with produce an additional path difference.

A thin glass plate is introduced in front of one of the double slits. What will happen to the fringe width?

Assertion In the YDSE set up shown in figure a glass slab is inserted in front of the slit S_(1) as shown in figure Then zero order maxima (where path difference =0) will lie above point O. Reason Glass slab will produce an extra path difference in the path of the ray passing through S_(1)

In Young's double slit experiment, match the following two coloums. {:(,"Column I",,"Column II"),("A","When width of one slit is slightly increased",,"p. maximum intensity will increase"),("B","When one slit is closed",,"q. maximum intensity will decrease"),("C","When both the sources are made incoherent",,"r. maximum intensity will remain same"),("D","When a glass slab is inserted in front of one of the slits",,"s. fringe pattern will displacement"):} Note Assume absorption from glass slab to be negligible

A glass slab is placed in the path of a beam of convergent light. The point of convergence of light

Assertion: White light is used in YDSE. Now, a glass slab is inserted in front of the slit S_1 . Then, red fringe will shift less (in upward direction) compared to violet. Reason: Refractive index for violet colour will be more.
