The correct answer is (b), lime juice.<\/p>\n
The Tyndall effect is the scattering of light by particles of a much smaller wavelength. It is named after the Irish physicist John Tyndall, who first observed it in 1869. The Tyndall effect is commonly observed in suspensions of particles in a fluid, such as milk or smoke. When light passes through a suspension, the particles scatter the light in all directions. This scattering is more pronounced for particles that are smaller than the wavelength of light.<\/p>\n
Chalk powder freshly mixed with water, few drops of milk mixed with water, and starch solution all show the Tyndall effect. This is because all of these substances contain particles that are smaller than the wavelength of light. Lime juice, on the other hand, does not show the Tyndall effect. This is because lime juice is a solution, and solutions do not contain particles that are smaller than the wavelength of light.<\/p>\n
In a solution, the solute molecules are evenly distributed throughout the solvent. This means that there are no large particles that can scatter light. As a result, when light passes through a solution, it is not scattered and the solution appears clear.<\/p>\n
In contrast, in a suspension, the particles are not evenly distributed throughout the medium. This means that there are large particles that can scatter light. As a result, when light passes through a suspension, it is scattered and the suspension appears cloudy.<\/p>\n","protected":false},"excerpt":{"rendered":"
