Tyndall Effect vs. Brownian Motion — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 2, 2023
Tyndall Effect relates to the scattering of light by colloidal particles, while Brownian Motion describes the erratic, random movement of particles in a fluid due to collision with molecules.

Key Differences
The Tyndall Effect is a phenomenon in which light is scattered by particles in a colloidal solution, making a beam of light visible in the medium. Brownian Motion, on the other hand, is the unpredictable, jittery motion of particles suspended in a fluid caused by collisions with fluid molecules.
While the Tyndall Effect is often observed in mixtures like colloids where particles are big enough to scatter light, the Brownian Motion can be seen in both colloidal solutions and true solutions where minute particles are incessantly jostling.
The Tyndall Effect serves as a primary method to determine if a mixture is a true solution or a colloid. Brownian Motion serves as evidence for the kinetic theory, demonstrating that atoms and molecules are always in motion.
In the Tyndall Effect, factors such as particle size and wavelength of light play pivotal roles in determining the intensity and angle of scattered light. In Brownian Motion, temperature and viscosity of the medium influence the rate and pattern of particle movement.
The Tyndall Effect is solely an optical phenomenon and does not imply any motion of particles. However, Brownian Motion is directly related to the physical movement of particles.
