DEFINE TYNDALL EFFECT?
Asked by pankajkvs665 | 21 Feb, 2018, 10:19: AM
answered-by-expert Expert Answer
Tyndall effect 
  • Tyndall effect can be defined as, the scattering of a beam of light by colloidal particles present in a colloidal solution.
 
                                                   

 

  • It can be observed when a fine beam of light passes through a small hole in the dark room. 
            This happens due to the scattering of light by the particles of dust or smoke present in the air.
  • The Tyndall effect can also be observed when the sunlight passes through the canopy of a dense forest. 
             In the forest, the mist contains tiny droplets of water which act as colloidal particles dispersed in the air.
