When a light wave confronts a matter, it diverges from its straight path and digresses into different directions. They two waves interfere each other so that the intensity of the resulting wave is I, which is given by the following relation. The coordinate system (x,y,z) is such that x is the direction of periodicity, y is the direction of translational invariance of the grating and z coincides with the optical axis of the objective.Thus, the grating vector g has only an x-component.Two different orthogonal polarizations are shown . Consider two waves that are emitted from two sources of intensities I1 and I2. Each wave also has the same amplitude, and they are in phase with one another. Thus, if the displacement produced by y1 is given by, then, the displacement produced by y2 would be, and the resultant displacement will be given by, The amplitude of the resultant displacement is 2a cos (/2) and therefore the intensity at that point will be if the waves have the same intensity Io, If the waves are of different intensities, then the resultant intensity is given by.
