Two identical coherent waves, each of intensity 'I', are producing an interference pattern. Find the value of the resultant intensity at a point
destructive interference.

Two identical coherent waves, each of intensity 'I', are producing an interference pattern. Find the value of the resultant intensity at a point constructive interference.

Why interference pattern not detected when two coherent sources are far apart.

Two coherent sources of light whose intensity ratio is 64:1 produce interference fringe. Calculate the ratio of of intensity of maximum and minmum in the interfernce fring system.

Two coherent sources whose intensity ratio is 81:1 produce interference fringe. Calculate the ratio of intensity of maximum and minimum in the fringe system.

Two coherent sources of light whose intensity ratio is 49:1 produces interference fringe. calculate the ratio of intensity of maximum and minimum in the fringe system.

Two coherent source of light,whose intensity ratio is 49:1 produces interference fringe.Calculate the ratio of intensity of maximum and minimum in the fringe system.
