Question

What is the Tyndall effect?

Answer 1

Hint:A colloid is a two-phase system consisting of a continuous phase(the dispersion medium) and the dispersed place (the particle or emulsion droplets) The particle size of the dispersed phase typically ranges from ${ 1 }$ nanometer to ${ 1 }$ micrometer. When light strikes them, the colloidal particles dissipate the light.

Complete step by step answer:
At whatever point the light goes through a colloidal arrangement or medium, the colloidal particles dissipate the light when light strikes them. This, thus, enlightens the way of the light i.e. the colloidal medium through which light passes. Colloidal particles in a way converge the light from a single beam to whole illuminate space.
For e.g. 1. We can see a film in a theater due to this Tyndall impact. The projector chips away at this wonder. At the point when a film is run on a projector, it anticipates itself on the big screen. We are able to see it on the screen due to the scattering of light by the dust (colloidal particles) particles present in the theatre.
2. 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.
3. Sunlight passes through a canopy of dense forest. In the forest, mist contains little droplets of water, which go about as particles of colloid scattered in the air.

Note: The possibility to make a mistake is that the scattering of light by particles in a medium without a change in wavelength is Rayleigh scattering, not the Tyndall effect. In Rayleigh scattering, the scattering particles are smaller than the wavelength of light whereas, in the Tyndall effect, the colloidal particle scattering is much more intense.
