Two coherent sources `S_(f)` and `S_(2)` (in phase with ech other) are placed at a distance of `2lambda` as shown where `lambda` is wavelength of sound. A detector moves on line `A B` parrallel to `S_(1)S_(2)`. If detector detects maximum intensity at finite distance from `O` at `theta = +- ((pi)/(n))`. Find `n`

Two coherent light sources S_1 and S_2 (lambda=6000Å) are 1mm apart from each other. The screen is placed at a distance of 25cm from the sources. The width of the fringes on the screen should be

Two coherent light sources S_(1) and S_(2) ( Lambda =6000 Å ) are 1.0 mm apart . the screen is placed in the distance of 25 cm from the sources .calculate the fringe width on the screen.

Two source of sound, S_(1) and S_(2) , emitting waves of equal wavelength 2 cm , are placed with a separation of 3 cm between them. A detector can be moved on a line parallel to S_(1) S_(2) and at a distance 24 cm from it. Initially, the detecor is equidistant from the two sources. Assuming that the waves emitted by the sources are in phase, find the minimum distance through which the detector should be shifted to detect a minimum of sound.
