Question
Classify the following as (a) transparent medium, (b) translucent medium, (c) opaque bodies. (i) an iron box (ii) a window pane (iii) a ground glass window (iv) wool (v) vacuum (vi) an iron nail (vii) muddy water (viii) butter paper (ix) diamond (x) marble

Answer

Transparent Medium allows most of the light energy to pass through it. For example glass, air, vacuum, diamond.
Translucent Medium partially allows the light energy to pass through it. For example, ground glass, muddy water, smoke, dust-filled air, butter paper.
Opaque Bodies do not allow light energy to pass through them. For example, bricks, stones, wood and articles made from it, wool .
