Airbags may Give False-Hight Breath Test Scores
The Tyndall Effect is a physics concept used to discuss something known as “colloidal suspensions.” Colloidal suspensions describe a homogenous substance consisting of submicroscopic particles dispersed in another. Unlike solutions, colloidal suspensions exhibit light scattering. A beam of light or laser, invisible in clear air or pure water, will trace a visible path through a genuine colloidal suspension, e.g. a headlight on a car shining through fog. This is knows as the Tyndall effect (after its discoverer, British physicist John Tyndall), and is a special instance of diffraction. Diffraction is a phenomenon that occurs with gases and liquids.
