Answer 1

Hint: In this question, we need to comment on the name of the body which should satisfy the given statement such that body which allows almost all the light to pass through it and does not reflect any light. For this we will recall the definitions of the mentioned terms in the options and try to relate the things with the given statement.

Complete answer:
An opaque body is a body which doesn’t allow any light through it. All the light is mostly absorbed or it may even reflect back. We cannot see through an opaque object. Some examples of opaque objects include wooden blocks, books and others.

A translucent object is one which allows some amount of light to pass through. We cannot clearly see through a translucent however we can see a silhouette of the object. Translucent glasses are used in bathroom mirrors.

A polished surface is the surface which can reflect all of the light falling on it. It is a perfect reflector of light. It doesn’t absorb or transmits light or even allow any light to pass through it. A breath example of a polished surface is a mirror or polished aluminum utensils.

A transparent body is one which allows almost all the light to pass through it and does not reflect any light falling on it.Some examples are glass and pure water

Hence, Option A is correct.

Note: Students should know the basic differences between transparent, translucent and opaque object. Students should also know the other terminologies involved in the chapter of light. Questions can also be asked to distinguish between different objects and classify them as transparent, translucent and opaque.
