Condition for Obtaining Clear and Broad Interference Bands

Condition for obtaining clear and broad interference bands (i) The screen should be as far away from the source as possible. (ii) The wavelength of......

Explain Huygen’s Principle

Huygen’s principle helps us to locate the new position and shape of the wavefront at any instant, knowing its position and shape at any previous......

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 photon of the incident light with the atoms or molecules. Let......

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.......

Explain on Wave Theory

Wave Theory: According to Huygens, light is propagated in the form of waves, through a continuous medium. Huygens assumed the existence of an invisible, elastic medium......
