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)`

Assertion: In the figure shown, zero order maxima will lie above point O. Reason: Zero order maxima normally means a point where path difference is zero.

In the set up shown in figure, the two slits S_1 and S_2 are not equidistant from the slit S. The central fringe at O is then

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.

Assertion: Two coherent sources S_1 and S_2 are placed in front of a screen as shown in figure. At point P, 10th order maxima is obtained. Then , 11th order maxima will be obtained above P. Reason: For 11th order maxima path difference should be more.

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.
