light scattering

Scattering of Light - When light passes through a substance or gas, a part of it is absorbed and the rest scattered away. The basic process in scattering is absorption of light by the molecules followed by re-radiation in different directi..

Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. A large number of mole..

Tyndall Effect - The earth's atmosphere is a heterogeneous mixture of minute particles. These particles include smoke, tiny water droplets, suspended particles of dust and molecules of air. When beam of light strikes such air particles, the path of the beam becomes visible. Similarly the ..

Scattering Due to Polarisation - When a light wave falls on a transparent solid, it causes the electrons in the solid to oscillate periodically in response to of the incident waves. Since these oscillating charges act coherently or cooperatively there is a lack of scatterin..

When a beam of white light is passed through a medium containing particles of size nearly equal to the wavelength of light, the beam gets scattered. This scattered light is seen in a direction perpendicular to that of incidence and is found to..

Nature of Light - Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles and this ..

Particulate matter affects local climate since particulates with a diameter greater than 1 micrometer scatter incoming light away from the Earth's surface. This affects weather and plant productio..

When a strong beam of light is passed through a colloidal solution, the path of the light becomes visible when viewed from a direction at right angle to that of the incident light. This occurs because the colloidal particles absorb light energy and then ..

Although a colloidal solution appears to be homogenous because the dispersed particles are too small too be seen, it can be distinguished from a true solution by its ability to scatter light. The scattering of light by colloidal sized particles is called the..
