Reflection

Experiment of Newton’s Rings Figure shows an experimental arrangement for producing and observing Newton’s rings. A monochromatic source of light is kept at the focus…

Newton’s Rings Theory In 1717, Sir Isaac Newton studied the pattern of the ring generated due to the interference of light. These rings are known…

An important application of interference in thin films is the formation of Newton’s rings. When a plano convex lens of long focal length is placed…

An important property of a resonant circuit is its bandwidth. Bandwidth is defined as the size of the frequency range that is passed or rejected…

Colors of thin films: Everyone is familiar with the brilliant colors exhibited by a thin oil film spread on the surface of water and also by…

Consider a transparent thin film of uniform thickness t and its\ refractive index μ bounded by two plane surfaces K and K′ (Figure). Fig: Interference…

Young’s double slit experiment: The phenomenon of interference was first observed and demonstrated by Thomas Young in 1801. The experimental set up is shown in…

Interference of light: Two slits A and B illuminated by a single monochromatic source S act as coherent sources. The waves from these two coherent…

Total Internal Reflection by Wave Theory: Let XY be a plane surface which separates a rarer medium (air) and a denser medium. Let the velocity…

Condition for sustained interference: The interference pattern in which the positions of maximum and minimum intensity of light remain fixed with time, is called sustained…
