Define the term tyndall effect ?
Answers
Answer:
The Tyndall effect is the phenomenon in which the particles in a colloid scatter the beams of light that are directed at them.
Explanation:
The Tyndall effect is the phenomenon in which the particles in a colloid scatter the beams of light that are directed at them. This effect is exhibited by all colloidal solutions and some very fine suspensions. Therefore, it can be used to verify if a given solution is a colloid. The intensity of scattered light depends on the density of the colloidal particles as well as the frequency of the incident light.
Answer:
When a beam of light is passed through colloidal solution placed in a dark room when the path of light illuminated when viewed at 90° right angle path of light is called tyndall effect.
Condition for tyndall effect:
- The diameter of particles of dispersed phase is not much smaller then the wavelength of light.
- Refractive index of dispersed phase and dispersion medium must be different from each other.
