Q. Two coherent sources $A & B$ emitting light of wavelength $λ$ are placed at position $(- D, 0)$ and $(- D, 3 λ)$ respectively. Here $D >> λ$ . The number of minima on $y$ -axis and maxima on $x$ -axis respectively are

6, 5

5, 6

4, 3

3, 4

Hence there are $6$ minimas of y axis and $5$ maxima of x-axis.
