Difference Between Interference And Diffraction Class 12. It is due to the super position. Path different between the end points of each section is λ 2 There are three sections therefore the path difference between point A and B is 3 λ 2.
Fringes are formed due to super position of light rays from the same source. The intensity of the edge of interference is always alike. It is due to the super position.
2Diffraction fringes are not of the same width.
Fringes are formed due to super position of light rays from the same source. So the phase difference between two independent light sources changes after 10-8 second. Whereas diffraction appears due to the superposition of the subordinate wavelengths. Fringes are formed due to super position of light rays from the same source.
