Tyndall Effect
The Tyndall effect which is also known as 'Tyndall's Scattering' is the concept that John Tyndall discovered about how light passes through colloidal and non-colloidal solutions. When light is shown through one medium versus another, the light may scatter differently depending on the contents inside. When particles are to small to block light, the light can not be seen through a medium for instance. Tyndall effect can be used to figure out whether liquids are colloids or not. -
Example of Tyndall Effect
https://www.youtube.com/watch?v=SoUmz8L87Z4 In this video you can see how he demonstrates how light passes through the medium with only water. The light is not visibly seen passing directly through the medium. However, when the light passes through the medium with soapy water, the light is visibly seen. The light reflects off of very small particles in the soapy water, but the particles are not consolidated enough in the water for the light to be seen.
