In the case of light waves from two coherent sources `S_(1)` and `S_(2)`, there will be constructive interference at an arbitrary point P, the path difference `S_(1)P - S_(2)P` is

In Young's double slit experiment, an interference pattern is obtained on a screen by a light of wavelength 6000 overset(circ)(A) coming from the coherent sources S_(1) and S_(2) . At certain point P on the screen third dark fringe is formed. Then, the path difference S_(1) P – S_(2) P in micron is

Two sound waves each of wavelength lamda and having the same amplitude A form two sources S_(1) and S_(2) interfere at a point P. If the path difference S_(2)P - S_(1)P = (lamda)/(3) , then the amplitude of the resultant were at P will be
