Figure shows two coherent sources S 1 -S 2 vibrating in same phase. AB is a straight wire lying at a far distance from the sources S 1 and S 2 . Let 
= 10 –3 . ∠ BOA = 0.12°. How many bright spots will be seen on the wire, including points A and B

Sol.
Say ‘n’ fringes are present in the region shown by ‘y’
⇒ y = n β = 
⇒ 
⇒ n = 
= 
> 1.
Hence; only one maxima above and below point O. So total 3 bright spots will be present (including point ‘O’ i.e. the central maxima).
