If two coherent light waves produce minima of fifth order, the path difference between the waves is-

The path difference between two waves is

The amplitudes of two coherent waves are vector quanti- ties. In the given table, Column I shows the phase differ ence between two coherent waves, Column II shows the path difference between them and Column III shows their resultant amplitudes. When is the phasor diagram at secondary maxima?

Waves emitted by two identical sources produces intensity of K unit at a point on screen where path difference between these waves is lamda . Calculate the intensity at that point on screen at which path difference is (lamda)/(4)

Between two coherent waves phase is:
