Understanding the Displacement of Fringes in Interference Patterns

One interesting aspect of interference patterns is the displacement of fringes. The displacement refers to the shift in the position of the fringes when certain conditions are changed. This displacement can occur due to several factors, including changes in the wavelength or angle of incidence of the waves. In Young’s double-slit experiment, for example, the […]

The Theory of Interference in Engineering Physics

One of the fundamental concepts in the theory of interference is the principle of superposition. According to this principle, when two waves meet at a point in space, the displacement of the medium at that point is the algebraic sum of the individual displacements caused by each wave. This means that if two waves are […]
