Difference Between Interference And Diffraction Class 12. Fringes are formed due to super position of light rays from the same source. Diffraction is due to the interaction of light coming from different parts of the same wavefront.
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. 2Diffraction fringes are not of the same width. Consider a train crossing the tunnel inside the tunnel the rays of the headlight will remain converged.
Consider a train crossing the tunnel inside the tunnel the rays of the headlight will remain converged.
It is the superposition of a continuous family of waves originating from each point on a single slit. Consider a train crossing the tunnel inside the tunnel the rays of the headlight will remain converged. Dec 16 2013 From the diagram path difference for first maxima is AD 3 λ 2 ie. Fringes have poor contrast.
