define Tyndall effect.
write its steps
Answers
The earth’s atmosphere is a mixture of smoke particles, tiny water droplets and air particles. When light falls on such colloidal particles, it is scattered (or deflected) thereby making the path of light beam visible. This phenomenon is called Tyndall effect. The light rays reach us after the deflection (scattering) from all these particles. Tyndall effect is also seen due to scattering of light through tiny droplets in mist or when sunlight enters a canopy of dark forest

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. The amount of scattering depends on the frequency of the light and the density of the particles.
