Riya plans an activity to observe how different particles affect the scattering of light. She passes a beam of white light through (i) clean air, (ii) a colloidal solution, and (iii) fog, and observes the colour and visibility of the scattered light.
(a) Identify the type of scattering observed in clean air, colloidal solution, and fog.
Answer:
Clean air -
Colloidal solution -
Fog-
