Difference Between Interference And Diffraction
Interference | Diffraction |
---|---|
Interference takes place between two separate wave fronts originating from two coherent sources. | Diffraction takes place when secondary wavelets originating from different point of the same wavefront. |
Fringe width may or may not be the same. | Fringe are not of the same width. |
All maximas are of same intensity. | Maximas are of varying intensity. |
The minimum intensity regions are usually almost perfectly dark. | The minimum intensity regions are not perfectly dark. |
