Answer 2

Question - Look at the pictures A, B and C given below and state which of them is transparent,

opaque and translucent.

Answer - A is transparent, B is translucent and C is opaque.

In the given picture, light completely passes through A. Thus it is transparent. Example - Glass.

When light is focussed on B, only some light passes through it. Neither it is blocked nor it is passes completely through B. Thus, it is translucent. Example plastic. Example - butter paper.

C completely blocks the light thus it is opaque. Example wall.
