Two coherent monochromatic point source S1 and S2 of wavelength λ=600nm are placed symmetrically on either side of the centre of the circle as shown in the figure. The sources are separated by a distanced d=1.8mm. This arrangement produces interference fringes visible as alternate bright and dark spots on the circumference of the circle. The angular separation between two consecutive bright spots is Δθ. Which of the following options is/are correct?

The angular separation between two consecutive bright spots decreases as we move from P1 to P2 along the first quadrant
A dark spot will be formed at the point P2
The total number of fringes produced between P1 and P2 in the first quadrant is close to 3000
At P2 the order of the fringe will be maximum
