Write the optical properties of colloids with diagram. – InterviewSolution

1.	Write the optical properties of colloids with diagram.
Answer» Solution :(i) Colloids have OPTICAL property. When a homogeneous solution is seen in the DIRECTION of light, it appears clear but it appears DARK, in a perpendicular direction. (ii) But when light passes through colloidal solution, it is scattered in all directions. (iii) This effect was first observed by Faraday, but investigations are made by Tyndall in detail, HENCE CALLED as Tyndall effect.
