Geeta placed three objects made of different materials as shown in the figure. She observed a bright spot of light at (II) but (III) would not get any spot. Then,


A (I) and (II) are made of transparent materials and (III) is made of opaque material.
B (I) is made of transparent material, (II) is made of translucent material and (III) is made of opaque material.
C (I) is made of transparent material, (II) is made of opaque material and (III) is made of either transparent or opaque or translucent material.
D (I) and (II) are made of opaque material and (III) is made of transparent material.


Answer can be B also because (iii) did not get any spot so it should be opaque and (ii) is translucent as a direct source of light is coming from the torch because (i) is transparent.

IF [I] WILL BE TRANSPARENT ,AS WE KNOW THAT THE MATERIALS WHICH ALLOW LIGHT TO PASS THROUGH THEM ARE CALLED TRANSPARENT SO IF WE CUT OUT A SQUARE TRANSPARENT SHEET FROM A ROLL OF TRANSPARENT ,SURELY THE LIGHT PATCH WILL PASS THROUGH[II]THEN THE [II] MATERIAL SHOULD BE SOMETING WHICH CAN NOT ALLOW LIGHT TO PASS TROUGH IT IT SHOULD BE OPAQUE AND THE LAST SQUARE[III] CAN BE MADE OUT FROM ANY MATERIAL,THUS IT WILL NOT CHANGE THE ANSWER.SO WE CONCLUDE THE CORRECT ANSWER IS C
