Question

mixture of milk and water appears blue when viewed by the reflected light and red when viewed by the transmitted light

Answer 1

because its a colloidal solution tyndall effect

Answer 2

The mixture of milk and water appears blue when viewed by the reflected light and red when it is viewed by the transmitted light due to the process Tyndall effect.

Detailed answer

The Tyndall effect is the scattering of light when a beam of light is passed through a colloidal solution.

• The smaller the particles, the shorter the wavelength so blueish

• The suspension particle that is the single or individual particle scatters the light that is transmitted to it.
• The amount of scattering depends on the frequency of the light transmitted on it and the total density of the particle.
• And we all know that milk is a colloid and so the Tyndall effect is a phenomenon associated with it.
