Question

what is Tyndall effect? two condition take place by Tyndall effect

Answer 1

TYNDALL EFFECT:

When a strong beam of light is passed through a true solution, we cannot see the light unless the eye is placed in the path but when the same beam of light is passed through a sol it becomes visible. What happens in this case of a sol is that the light scatters from the surface of the colloidal particles and reaches our eyes. This phenomenon is called the Tyndall effect.  

If these two conditions are satisfied then we can observe the Tyndall effect:

>>When the diameter of the dispersed particles is little smaller than the wavelength of light used.

>>The refractive indices of the dispersion medium and the dispersed phase vary in magnitude to a large scale.

Answer 2

HERE IS YOUR ANSWER....

The phenomenon of scattering of light by the colloidal particles give rise to Tyndall Effect.

• Tyndall effect can observe we the sunlight passes through the canopy of sense forest.

• When a fine beam of sunlight enters a dark room.
