Question

" The phenomenon due to which colloidalparticles scatter blue colour in white light iscalled Tyndall effect."

Is blue light "only" scattered in Tyndall Effect?

Answer 1

Tyndall effect is the phenomenon of scattering of light by the small particles of colloid or suspension because of which the path of light is illuminated. The tiny particles scatter the beam of light and make its path visible. The color of the scattered light depends on the size of the scattering particles as well as on the wavelength of the light. Larger particles like dust particles and water droplets scatter all colours equally. In this case the scattered light will appear white.
But smaller particles scatter shorter wavelengths(blue) much more than longer wavelengths.
