Which of the following pairs is an example of translucent bodies?

Step 1: Analyze the question The question asks for a pair of translucent bodies.

Step 2: Key concept Materials are classified by how they transmit light:

• Transparent: allow light through freely, so you can see clearly through them (clear water, clear glass, air).
• Translucent: allow some light through, but scatter it, so objects behind look blurred or unclear (frosted glass, waxed paper, oiled paper, tracing paper).
• Opaque: allow no light through (wood, metal, brick, cardboard).

Step 3: Check each option

• A. Cardboard and moon: Both are opaque. The moon is a non-luminous body that reflects sunlight. ✗
• B. Clear water and glass: Both are transparent. ✗
• C. Frosted glass and waxed paper: Both let light through but scatter it, so you cannot see clearly through them. Both are translucent. ✓
• D. Oiled paper and brick: Oiled paper is translucent, but brick is opaque, so the pair is mixed. ✗
• E. Wood and metal sheet: Both are opaque. ✗

Step 4: Answer The only option in which both members are translucent is C. Frosted glass and waxed paper.

Exam tip: Remember the order of light passage: Transparent = clear view, Translucent = blurry view, Opaque = no view. In "pair" questions, check that both items fit the category. Option D is a common trap because oiled paper is translucent but brick is not.
