Question

What is Tyndall effect? What is the reason for Tyndall effect? Give 2 applications from daily life.

Answer 1

The Tyndall Effect is the effect of light scattering in colloidal dispersion, while showing no dispersion in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid.

When the visible light encounters scattered particles in a colloid like say dust in air or water light is reflected off of particles that are slightly below or near the size of a wavelength of light. Depending on how much light a particular material absorbs, a different color is emitted. Shorter wavelengths of light tend to be scattered more than longer wavelengths.
Applications

The concept is determining the strength of concentrations ( Nephelometer )
The headlights of vehicles work on the principle of Tyndall effect
Sunlight visible in dense forest or blue colour of sky is also an example/application of this effect.

Answer 2

Answer:

What is Tyndall effect ?

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.

What is the reason for Tyndall effect?

As with Rayleigh scattering, blue light is scattered more strongly than red light by the Tyndall effect.
