Figure shows two coherent microwave source `S_(1)` and `S_(2)` emitting waves of wavelength `lamda` and separated by a distance `3lamda` for `lamdalt lt D` and `yne0`. The minimum value of y for point P to be an intensity maximum is `(sqrt(m)D)/(n)` determine the value of m+n, if m and n are coprime numbers.

Figure shows two coherent sources S_1 and S_2 which emit sound of wavelength lamda in phase. The separation between the sources is 3lamda . A circular wire at large radius is placed in such a way that S_1 S_2 lies in its plane and the middle point of S_1 S_2 , is at the centre of the wire. Find the angular positions 0 on the wire for which constructive interference takes place.

Two coherent point sources S_1 and S_2 vibrating in phase emit light of wavelength lamda . The separation between them is 2lamda . The light is collected on a screen placed at a distance Dgt gt lamda from the slit S_1 as shown. The minimum distance, so that intensity at P is equal to the intensity at O
