What is Tyndall effect? Explain with an example.
Answers
The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. ... As with Rayleigh scattering, blue light is scattered more strongly than red light by the Tyndall effect.
The scattering of light hy particles in its path is called Tyndall effect. When a beam of light enters a smoke-filled dark room through a small hole, then it's path becomes visible to us The tiny dust particles present in the air of room scatter the beam of light all around the room. Thus, scattering of light makes the particles visible. Tyndall effect can also be observed when sunlight passes through a canopy of a dense forest. Here, tiny water droplets in the mist scatter light.
