Experiment: Reflection of a Plane Wave Front at a Plane Surface Reflection of a plane wave front at a plane surface Let XY be a plane reflecting surface and AB be a plane wavefront incident on…
Define and Describe on Wave Front When a stone is dropped in a still water, waves spread out along the surface of water in all directions with same velocity. Every particle…
Describe on Raman Spectrum Raman Spectrum: The Raman effect can be easily understood, by considering the scattering of the photon of the incident light with the atoms or molecules.…
What is Raman Effect? In 1928, Sir C.V. Raman discovered experimentally, that the monochromatic light is scattered when it is allowed to pass through a substance. The scattered light…
Applications of Raman Spectrum Raman spectroscopy or Raman Spectrum is used in many varied fields, like, non-destructive, microscopic, chemical analysis and imaging is required. (i) It is widely used…
Describe on Scattering of Light Lord Rayleigh was the first to deal with scattering of light by air molecules. The scattering of sunlight by the molecules of the gases in…
Explain on Quantum Theory The electromagnetic theory, however, failed to account for the phenomenon of photo electric effect. In 1900, Planck had suggested that energy was emitted and absorbed,…
Define Tyndal Scattering When light passes through a colloidal solution its path is visible inside the solution. This is because, the light is scattered by the particles of…
What is Electromagnetic Theory? Maxwell showed that light was an electromagnetic wave, conveying electromagnetic energy and not mechanical energy as believed by Huygens, Fresnel and others. Electromagnetic Theory covers…
Explain on Corpuscular Theory Corpuscular Theory: According to Newton, a source of light or a luminous body continuously emits tiny, massless (negligibly small mass) and perfectly elastic particles called corpuscles.…
