what is tyndall effect?

Dear Student,

Tyndall effect is the phenomenon of scattering of light by the particles of colloid or suspension because of which the path of light is illuminated. The tiny particles scatter the beam of light and make its path visible. For example: Tyndall effect can be observed when
sunlight passes through the canopy of a dense forest. In the forest, mist contains tiny droplets of water, which act as particles of colloid dispersed in air.

The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or particles in a fine suspension. It is named after the 19th century physicist John Tyndall. It is similar to Rayleigh scattering, in that the intensity of the scattered light depends on the fourth power of the frequency, so blue light is scattered much more strongly than red light. An example in everyday life is the blue colour sometimes seen in the smoke emitted bymotorcycles, particularly two stroke machines where the burnt engine oil provides the particles.

In a simple way . Tyndall Effect is the scattering of light by particles in its path.

For example, When a beam of sunlight enters a dusty room through a window, then its path becomes visible to us .This is because the tiny dust particles present in the air of a room scatter the beam of light all around the room.

Tydall effest can also be observed when sunlight passes through the canopy of a dense forest.

The phenomenon of scattering of light by the colloidal particles is known as Tyndall Effect. This effect can be observed when:-

1) A fine beam of sunlight enters a room containing suspended particles of dust, the path of the beam of light is visible. It is due to the scattering of light.

2) Sunlight passes through a canopy of dense forest,. In the forest, mist contains tiny droplets of water, which act as particles of colloid dispersed in air

TYNDALL EFFECT :

The Tyndall effect , also known as Tyndall scattering , is scattering of light by particles in a colloidal solution.It is named after the 19th century physicist , John Tyndall .

Tyndall Effect is observed even in our daily life.some examples are :

1) A fine beam of sunlight enters a room containing suspended particles of dust, the path of the beam of light is visible. It is due to the scattering of light by the dust particles.

2) Sunlight passes through a canopy of dense forest,. In the forest, mist contains tiny droplets of water, which act as particles of colloid dispersed in air.

Whenever light passes through a colloidal solution or medium, the colloidal particles scatter the light when light strikes them. This in turn illuminates the path of the light i.e. the colloidal medium trough which light passes. Colloidal particles in a way converges the light from a single beam to a whole illuminate space.
 
For e.g. we are able to see a movie in a theatre because of this Tyndall effect. Projector works on this phenomenon. When a movie is run on a projector, it projects itself on the big screen. We are able to see it on the screen due to scattering of light by the dust (colloidal particles) particles present in the theatre.
 
 
Hope it helps

Tyndell effect is the csatering of ligt from the collidal particles

 The Tyndall effect is the scattering of light as a light beam passes through a colloidal. The individual suspension particles scatter and reflect light, making the beam visible. The amount of scattering depends on the frequency of the light and density of the particles.
Examples:

The visible beam of headlights in fog is caused by the Tyndall effect. The water droplets scatter the light, making the headlight beams visible.
