Question:
Milk-water mixture when viewed by the reflected light appears in which colour?
Milk-water mixture when viewed by the reflected light appears in which colour?
Show Hint
Colloidal particles scatter shorter wavelengths more effectively, which is why scattered light often appears blue.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Identify the phenomenon involved.
Milk-water mixture is a colloidal solution.
Colloidal particles scatter light due to: Tyndall effect
Step 2: Understand scattering of light.
Smaller wavelengths scatter more effectively than larger wavelengths.
Among visible colors, blue light has shorter wavelength and is scattered more strongly.
Step 3: Appearance in reflected light.
Since blue light is scattered most, the reflected light appears: Blue
Step 4: Final conclusion.
Hence, the milk-water mixture appears \[ \boxed{\text{Blue}} \] in reflected light.
