Question

A cellophane paper is an example of-
(A) an opaque object
(B) a translucent object
(C) a transparent object
(D) a luminous object

Answer 1

Hint
Any material, in this case the paper, is classified based on the quantity of light rays that they allow to pass through them. The objects that are classified based on this are of three types. They are opaque objects, translucent objects and transparent objects.

Complete step by step solution
In the case of the transparent object, the object allows more or less all the light rays that are passed through them, example: air, water, glass, light bulbs, etc. in case of translucent object, the object through which the light passes through allows only some of the light rays to pass through them and the remaining light rays are scattered in all direction, example: shear fibre, cellophane. Opaque material does not allow any light to pass through them, example: rock, wall, etc.
Cellophane paper is a transparent material which is formed by cellulose that has low absorption to oxygen, moisture, oil, grease, and bacteria. It is a polymeric cellulose material made from wood, cotton, hemp. The raw material that is used in making this paper is called the dissolving pulp, which is white like cotton. Cellophane paper permits light to pass through it. Therefore, cellophane is an example of a transparent object.
Hence, the option (C) transparent object is the correct answer.

Note
A luminous object is a type object that discharges light on its own, that object is itself a light source, some of best suited examples are sun, star, light bulb, flame, etc. The luminous object emits light energy which comes in the form of packets called the quanta. These packets then form into photons.
