The Tyndall effect, also known as Willis–Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension. It is named after the 19th-century physicist John Tyndall. It is similar to Rayleigh scattering, in that the intensity of the scattered light depends on the fourth power of the frequency, so blue light is scattered much more strongly than red light. An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles, in particular two-stroke machines where the burnt engine oil provides these particles.

Under the Tyndall effect, the longer-wavelength light is more transmitted while the shorter-wavelength light is more reflected via scattering. The Tyndall effect is seen when light-scattering particulate-matter is dispersed in an otherwise-light-transmitting medium, when the cross-section of an individual particulate is the range of roughly between 40 and 900 nanometers, i.e., somewhat below or near the wavelength of visible light (400–750 nanometers).

It is particularly applicable to colloidal mixtures and fine suspensions; for example, the Tyndall effect is used in nephelometers to determine the size and density of particles in aerosols and other colloidal matter (see ultramicroscope and turbidimeter).

The phenomenon of scattering of light when a light beam passes through a fluid (colloid) is known as Tyndall effect, while the random movement of particles in a fluid (colloid) is the Brownian motion, it occurs due to the collisions of the particles.

◆ Tyndall effect -

Tyndall effect is scattering of a beam of light by the particles of a colloid.

◆ Brownian motion -

Brownian motion is random motion of fluid particles bombarding on each other.

# For example -

Milk being a colloid (liquid fat in water), shows Tyndall effect.

When beam of light is passed through milk, it's scattered through the milk.

Here, path of light becomes visible due to Tyndal effect.
