Question

Can anyone explain about Tyndall cone?​

Answer 1

Answer:

In discussions about light scattering, the converging beam is called a "Tyndall cone". ... The spots are inherently fuzzy because light scattering produces fuzzier images than light reflection. The particles are in Brownian motion in most kinds of liquid and gas colloids, which causes the movement of the spots.

Answer 2

Explanation:

The illuminated path of beam is called Tyndall effect cone. The phenomena is observed when a beam of light is projected in a cinema hall and it becomes visible due to scattering by colloidal dust particles. The diameter of the dispersed particles is not much smaller as compared to wavelength of light used.
