Ever wondered about the reason for the light from the edge of clouds or from windows
\nin your darkroom or the beautiful sunlight coming through trees or the blue color of
\nsmoke from your motorcycle engine or the blue color of the sky? These mesmerizing
\nphenomena are known as the Tyndall effect<\/a>.
\nTo understand the Tyndall effect, we need to know about colloid and suspension.
\nA mixture of solid in a liquid where the solid is evenly dispersed and does not undergo
\nsedimentation. The solid is the dispersed phase whereas the liquid is the dispersion
\nmedium. The size of particles ranges from 1 nm- 1000 nm and are invisible to naked
\neyes. Such a homogenous mixture is called colloid. Some examples of colloid: Dust,
\nfog, etc.
\nA mixture of solid in a liquid where the solid is insoluble in liquid but will eventually settle
\nat the bottom. The solid is the dispersed phase whereas the liquid is the dispersion
\nmedium. The size of particles ranges between 0.5um to 5 um and are visible to naked
\neyes. Such a heterogeneous mixture is called suspension. One example for suspension
\nis muddy water. So after knowing about the colloid and suspension, it is easier to
\nunderstand Tyndall effect
\nThe effect of light scattering through a colloid when a beam of light is passed through it
\nis called the Tyndall effect. A colloidal solution or substance such as fog is made of
\nscattered particles. When light is passed through such a substance, it colloids with the
\nparticles like water and dust in the air. Due to this collision, the beam of light is scattered
\ncausing the effect of a visible light beam. John Tyndall who was a British physicist was
\nthe first to describe this effect in the 19th century.
\nAn example of the Tyndall Effect:
\nWhen you travel in the car, sometimes you will not be able to see far because of the fog
\nand the car headlights are not able to shine all the way through the fog. This is due to
\nthe Tyndall effect. Fog is a colloidal substance. From above we already know that when
\na beam of light comes in contact with scattered particles like fog and dust it undergoes
\ndispersion which leads to scattering of light in multiple directions. Hence the Tyndall
\neffect.
