Description : Light scattering takes place in – (1) Colloidal solutions (2) Acidic solutions (3) Electrolyte solutions (4) Basic solutions
Last Answer : (1) Colloidal solutions Explanation: Light scattering in colloidal solutions or particles in suspension is known as Tyndall Effect. It is similar to Rayleigh scattering, in that the intensity of the ... fourth power of the frequency, so blue light is scattered much more strongly than red light.
Description : Light scattering takes place in (1) Colloidal solutions (2) Acidic solutions (3) Electrolyte solutions (4) Basic solutions
Last Answer : Colloidal solutions
Description : In mirrors the back surface is coated with a thin layer of (1) Mercury (2) Silver (3) Red oxide (4) Silver nitrate
Last Answer : (2) Silver Explanation: In a spherical mirror, one of the two curved surfaces is coated with a thin layer of silver followed by a coating of red lead oxide paint. Thus, one side of the spherical minor is opaque and the other side is a highly polished reflecting surface.
