Question

explain when a beam of light is passed thru a colloidal sol the path beam

Answer 1

(i) When a beam of light is passed through a colloidal solution, then scattering of light is observed. This is known as the Tyndall effect. This scattering of light illuminates the path of the beam in the colloidal solution. ... (iii) The colloidal particles are charged and carry either a positive or negative charge.

Answer 2

Answer:

When a light passes through a true solution, containing solute particles of size less than 1 nm, the path of the light is not visible. If the light is passed through a colloidal solution, the path of the light through the.dispersion medium becomes visible due to the scattering of the light. This is the optical property of the colloids.
