Two coherent monochromatic point source S1 and S2 of wavelength λ=600 The sources are separated by a distance d = 1.8 mm. 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?

[JEE Adv 2017 P2]

The total number of fringes produced between P1 and P2 in the first quadrant is close to 3000
A dark spot will be formed at the point P2
At P2 2 the order of the fringe will be maximum
The angular separation between two consecutive bright spots decreases as we move from P1 and P2 he angular separation between two consecutive bright spots decreases as we move from
