TYNDALL EFFECT

 TYNDALL EFFECT :

-Phenomenon of scattering light

happens mostly in colloids in which the particles scatter light in all direction

-Can be observed by Ultra microscope

Condition:

*wavelength of light < diameter of colloidal particles

* NDM-NDP

The difference should be of large value

N-Refractive index, DM- Dispersion Medium, DP- Dispersed medium

Discovered by John Tyndall, faraday

Diffrention was given by Zsigmondy

The differentiation was the particles do not scatter when the solution is a True solution because the particles are too small to scatter light
