The complete question is:

Which of these would not show the Tyndall effect? Justify your answer.

(a) Smoke

(b) Rubber

(c) Face cream

(d) Air

Air would not show Tyndall effect.

• Tyndall effect is the scattering of a beam of light in a solution.
• Tyndall effect only happens in colloidal solution and depends on the density of the solution.
• Since air particularly pure air is not a colloidal solution instead it's a true solution, therefore it would not show the Tyndall effect.
• All the other things mentioned will show Tyndall effect depending on their composition because they are colloidal solutions.
