Question

In Tyndall effect, the colour of light that is scattered depends on

• A. Size of the scattering particle
• B. Colour of the scattering particle
• C. Shape of the scattering particle
• D. Both (a) and (c)

Answer 1

The correct option is A

Size of the scattering particle

The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension. The wavelength of light scattered should be nearly equal to the size of the particle.
