AnsWer :-
An experimental set up by Tyndall is used to observe water clarity.
Option (b) is correct.
Explanation:
◼ In the commercial labs, the Tyndall set up is used to determine the water clarity.
◼ In this effect, light is passed through the colloidal solution.
◼ As the light passes through the solution it scatters in a colloidal solution, but if the solution is true then no scattering occurs.
◼ Tyndall effect is used to determine if a solution is a true or colloidal solution.

An experimental setup devised by Tyndall is used to observe water clarity.
Option (b) is correct.
Explanation:
- This phenomenon is called the Tyndall effect.
- In this experiment, light is passed through a solution to determine its clarity.
- If the light passing through the solution scatters into different wavelengths then the solution is colloidal.
- If the light passes straight and does not scatter then the solution is true.
