Your answer

★ Observations
-----------------------

(1) When a break of light is passed through a true solution
------------------------------------------------------------------------------------

● Light just passes through the true solution and is not reflected by the particles of the true solution,.
● Therefore, the Tyndall effect is not observed.

(2) When a beam of light is passed through a colloid
----------------------------------------------------------------------------

● The light is scattered by the colloidal particles, the path of the light is visible.
● The Tyndall effect is observed.

(3) When a beam of light is passed through a suspension
-----------------------------------------------------------------------------------

● Light hardly passes through the soapwort particles.
● The Tyndall effect is not observed.

HOPE IT HELPS

Answer 2

Answer:

When a beam of light is passed through a colloidal solution, then a 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.

When passed through suspension, path of light ray is visible due to scattering of light beam by large particles
