what is the tyndal effect?
Asked by | 14th Jul, 2008, 04:19: PM
Colloidal particles are much larger than atoms or molecules. It follows from scattering theory that Tyndall scattering (by colloidal particles) is much more intense than Rayleigh scattering (by atoms or molecules). Tyndall scattering can be used to determine the size of colloidal particles. Tyndall scattering is also often used to describe light scattering by macroscopic particles such as dust in the air. However, this phenomenon is more like reflection, as the macroscopic particles become visible in the process.
