Answer 1

The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible.

Ex1 Shining a flashlight beam into a glass of milk is an excellent demonstration of the Tyndall effect. You might want to use skim milk or else dilute the milk with a bit of water so you can see the effect of the colloid particles on the light beam.

EX2 The visible beam of headlights in fog is caused by the Tyndall effect. The water droplets scatter the light, making the headlight beams visible.
