Question

Which of the following are the examples of transparent materials:
A: Glass
B: Water
C: plastic
D: All of these

Answer 1

The materials which allow the light to pass through them easily without causing the scattering of light are known as transparent materials. We can see through them clearly.

Complete step by step answer:
Glass is also known as an amorphous solid. This means it is a state of matter in which all the atoms and molecules are firmly locked onto their respective places, but instead of forming neat and orderly crystals, they arranged themselves randomly. Due to this, glasses are mechanically rigid like solids, and yet they have the disordered arrangement of the molecules like liquids. Consequently, photons of visible light travel through glass instead of being absorbed or reflected, making glass transparent.
Water allows the light to pass through it and it does not tend to absorb wavelengths of visible light instead these wavelengths or the rays of light are reflected back by water. This is because the electrons present in the water are much similar to that of the electrons present in the visible light rays. Hence, from the above discussion, it is clear that water is a transparent material.
Plastic is also transparent due to its structure at the molecular level which does not restrict the rays of light to travel through it.
As we can see that all the given materials that are glass, water and plastic are transparent

So, the correct answer is Option D.

Note:
Materials can be classified into three categories on the basis of their abilities to permit light to pass through them.
The three categories are:-
i) Transparent materials
ii) Translucent materials
iii) Opaque materials.
