Two coherent narrow slits emitting light of wavelength `lamda` in the same phase are placed parallel to each other at a small separation of `3lamda` the light is collected on a screen S which is placed at a distance `D(gt gt lamda)` from the slits the smallest distance x such that the P is a maxima.

Two coherent narrow slits emitting light of wavelength lambda in the same phase are placed parallel to each other at a small separation of 2lambda . The light is collected on a screen S which is placed at a distance D(gtgt lambda ) from the slit S_1 as shown in figure. Find the finite distance x such that the intensity at P is equal to intensity O. .

Two coherent narrow slits emitting sound of wavelength lambda in the same phase are placed parallel to each other at a small separation of 2 lambda . The sound is detected by moving a detector on the screen at a distance D ( gt gt lambda) from the slit S_1 as shown in figure. Find the distance y such that the intensity at P is equal to intensity at O.

Two coherent narrow slits emitting sound of wavelength lambda in the same phase are placed parallet to each other at a small separation of 2 lambda . The sound is delected by maving a delector on the screen at a distance D(gt gt lambda) from the slit S_(1) as shows in figure. Find the distance y such that the intensity at P is equal to intensity at O .
