Understanding Newton’s Rings: Formation, Applications, and Experimental Setup
Formation of Newton’s Rings When a convex lens is placed on a flat glass surface, a thin layer of air gets trapped between them, creating a small air wedge. When light is incident on this air wedge, it undergoes multiple reflections and refractions, leading to the formation of a series of concentric rings of alternating […]
Exploring Fresnel’s Biprism: An Optical Instrument for Interference Phenomena
Introduction to Fresnel’s Biprism Fresnel’s biprism is a fascinating optical instrument that was invented by the French physicist Augustin-Jean Fresnel in the early 19th century. This device is used to study the phenomenon of interference, which occurs when two or more waves superpose and create regions of constructive and destructive interference. The biprism consists of […]
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 […]
