A beam of light parallel to central line...

A beam of light parallel to central line AB is incident on the plane of slits. The number of minimum, obtained on the large screen is `n_1`. Now if the beam is tilted by some angle `(!= 90^@)` as shown in figure, then the number of minima obtained is `n_2`. Then,

A

`n_1 =n_2`

B

`n_1gtn_2`

C

`n_2gtn_1`

D

`n_2` will be zero.
