"The Tyndall Effect refers to the reflection of light as it comes in contact with small particles in a translucent medium. It involves the scattering of light in different colors depending on how short or long a particular wavelength is. For example, the Tyndall Effect can describe the haze seen as light travels through a window covered in dust or the light from a flashlight comes in contact with fog in the air. In these situations, dust and water droplets cause the light to be reflected in a scattered pattern towards the viewer."
