Tyndall Effect
Operation: Press the "Start" button to observe the Tyndall phenomenon. Function Overview: The exhibit consists of a laser and a tube of colloid. Visitors press the start button to activate the laser, and the laser path becomes visible in the colloid. Scientific Principle: When a beam of light passes through a colloid, a bright "path" appears in the colloid when observed perpendicular to the incident light. This phenomenon is called the Tyndall phenomenon, also known as the Tyndall effect, Tyndall phenomenon, or Tyndall effect. During light propagation, when light strikes particles, if the particles are many times larger than the wavelength of the incident light, reflection occurs; if the particles are smaller than the wavelength of the incident light, scattering occurs. In this case, the observed light waves radiate around the particles in all directions, called scattered light or opalescence. The Tyndall effect is the scattering of light, also known as the opalescence phenomenon. Since solution particles generally do not exceed 1 nm, colloid particles are between solute particles in solution and particles in suspension, with sizes ranging from 1 to 100 nm. This is smaller than the wavelength of visible light (400 nm to 700 nm), so when visible light passes through a colloid, significant scattering occurs. For true solutions, although molecules or ions are even smaller, the intensity of scattered light decreases significantly as the volume of scattering particles decreases, so the scattering of light by true solutions is very weak. In addition, the intensity of scattered light increases with the concentration of particles in the dispersion system.
