what is tyndall effect?how it is caused?what are the condition required to see the tyndall effect?
Answers
Answer:
Tyndall effect is the effect in which scattering of light is seen by the particles present in colloid or in very fine suspension. Conditions that are necessary for Tyndall effect to take place are: The diameter of the particles in dispersed phase should not be much smaller than the wavelength of light used.
Answer:
Definition-Tyndall effect, also called Tyndall phenomenon, scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window.
Cause-It is caused by reflection of the incident radiation from the surfaces of the particles, reflection from the interior walls of the particles, and refraction and diffraction of the radiation as it passes through the particles. Other eponyms include Tyndall beam (the light scattered by colloidal particles).
The condition required to see the tyndall effect-
Conditions that are necessary for Tyndall effect to take place are: The diameter of the particles in dispersed phase should not be much smaller than the wavelength of light used. The difference between the refractive indices of the dispersed medium and dispersed phase should be large.
