Question

What do you mean by tyndal effect

Answer 1

Answer:

$\huge\bold\green{answer}$

Tyndall effect, also called Tyndall phenomenon, scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window. ... The effect is named for the 19th-century British physicist John Tyndall, who first studied it extensively.

Answer 2

Answer:

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.

Explanation:

Another way to look at it is that longer wavelength light is transmitted, while shorter-wavelength light is reflected by scattering.

Examples

1-Shining a flashlight beam into a glass of milk

2-The visible beam of headlights in fog is caused by the Tyndall effect.
