Q. Which one of the following will NOT show the Tyndall effect?
Tyndall Effect
The Tyndall effect is when light is scattered by particles of matter in its path. It makes a beam of light visible by lighting the particles.
Under the Tyndall effect, the longer-wavelength light is more transmitted while the shorter-wavelength light is more reflected by scattering. In effect, blue light is scattered much more strongly than red light.
The Tyndall effect is seen when light-scattering particulate matter is dispersed in an otherwise light-transmitting medium, when the diameter of an individual particle is the range of roughly between 40 and 900 nm, i.e. somewhat below or near the wavelengths of visible light (400–750 nm).
The blue of a clear sky, and the blue of blue eyes is caused by the Tyndall effect, not by a pigment. Its named after John Tyndall. Tyndall effect can also be observed when sunlight passes through the canopy of a dense forest.

- Lime juice
- Few drops of milk mixed with water
- Starch solution

The size of the particles is what distinguishes a colloid from a true solution. For a mixture to be a colloid, the particles must be in the range of 1-1000 nanometers in diameter.Examples of familiar colloids include butter, milk, smoke, fog, ink, and paint. Cytoplasm is another example of a colloid.
