Butter paper is an example for …… objects.
A. A transparent
B. A translucent
C. An opaque
D. A luminous

Hint: The butter paper allows a partial transfer of light through it. So when we see through the butter paper, things appear blurred and we cannot clearly see. Recall the difference between transparent, translucent and opaque objects to answer this question.

Complete answer:
We know that the butter paper is smooth, heat resistant, and non-sticky and absorbs very less amount of water. It is used in bakery or as a grease proof paper. The butter paper allows a partial transfer of light through it. So when we see through the butter paper, things appear blurred and we cannot clearly see.

Now, let us see the difference between transparent, translucent, opaque and luminous objects.In a transparent object, the incident light gets totally transmitted through the object. Thus, we can clearly see the objects through the transparent object. Since the butter paper does not allow us to see through it clearly, the butter paper is not a transparent object.

In opaque objects, the incident light does not pass through the object. Therefore, we cannot see through the opaque objects. So, the butter paper is not opaque.A luminous object is the object in which it glows when kept in sunlight or any exposure of light. The butter paper is not a luminous object.

In a translucent object, the incident light gets partially transmitted through it. Thus, we can see the things through the translucent paper but they appear blurred. Therefore, the butter paper is definitely an example of the translucent objects.

So, the correct answer is option B.

Note:Some of the butter papers are actually opaque to the sunlight. To answer this question, students must know the difference between transparent, translucent, and opaque materials. The glass is an example of a transparent object but the glass also reflects some fraction of light falling onto it.
