The transparent objects they are those that the light passes through completely. One consequence of this is that the figures behind them can be seen through these objects, without being deformed or transformed; that is, they look just the way they are.
An example of a transparent object is a glass window. Through it you can see clearly, without change or distortion, mountains, streets, people and animals. But: can you see through a wall? Of course not! The wall is an opaque object.
An opaque object does not let light pass through it, so the figures behind this object cannot be seen. An example of an opaque object is a person; if you place your back to the sun you will be able to see your shadows on the floor or on a wall, that is, the sunlight does not pass through the skin and bones.
Almost all living beings are opaque beings. However, there are few exceptions, such as jellyfish, which when placed on the surface of the water are practically invisible because they are almost transparent..

Transparent objects have the following characteristics:
Light can completely pass through transparent objects. Light is then said to be transmitted without scattering by these objects. Other materials can transmit light, but also scatter it, such as frosted glass.
A portion of the light can be reflected by some transparent objects. Due to this characteristic, images of objects located around it can be seen in the crystal clear water..
Due to the property of transparent objects to be penetrated by light, objects located behind them can be seen clearly, without distortion. Thus, you can see behind a cellophane paper the different foods that are kept in the bags made with this transparent material..
Transparent objects take their color from the light that passes through them. The light that illuminates us is white, so the color of transparent objects is usually white. But if we illuminate them with a blue light, they will look that color.
Transparent objects do not produce shadows, since this is produced by opaque objects, which are not crossed by light.
Some examples of transparent objects or substances are listed below:
-Water
-Glass
-Air
-Ocular cornea
-Celofan paper
-Sapphire
-Fishbowl
-Polycarbonate plastic
-Acrylic plastic
-Polyurethane resins
-Epoxy resins
Water is a substance usually in a liquid state, but it can also exist in a solid state and in a gaseous state. The water condenses in the freezer to become ice, a solid, at 0 ° C. And it boils in the pots to transform into water vapor, a gas, at 100 ºC.
The transparency of the water is demonstrated by looking at the glass of water that we drink and by observing the fish, algae, or stones that lie on the floors of lakes and rivers. Both water vapor and ice are transparent substances; however, they may become translucent or opaque.
For example, there are ice cubes and blocks that are extremely clear, clean. On the other hand, there are blocks of ice that present whitish or bluish tones, through which it is impossible to distinguish any object on the other side of the ice..
Air is a transparent substance whose presence is not very evident through your vision or touch. But we feel it when the breeze or the wind blows, which is air in motion, or when we are missing and suffocation is felt. The air surrounds the man on all four sides and it is said that he is immersed in it.
If the air were not transparent, we would live surrounded by a constant and eternal dry mist, without being able to visualize any object in our vicinity. Fortunately, air molecules do not scatter light, so light passes through it unaltered. Even worse, in a world without transparent air darkness would probably reign during the days.
Glass is a transparent, hard, rigid and breakable object. It is used in the elaboration of numerous objects of daily use, such as bottles for liquids, jars for food, glasses, plates, windows of houses and buildings, greenhouses, etc..
Glass uses natural elements as raw material, such as sand, limestone and sodium carbonate, which are melted in furnaces at high temperatures to form it..
In addition to ordinary glass, there are other types of glass, such as borosilicate glass. This is used in refractory utensils, that is, in those glass objects that withstand high temperatures and sudden changes in temperature. Meanwhile, optical glass is used in the manufacture of lenses..
If the optical glass was not transparent, the visually impaired would not be able to see at all.
It is a disk-shaped membranous structure that lines the front of the eye. In addition to fulfilling a protective function, the cornea fulfills a lens function and together with the other ocular lens, the crystalline lens, they carry light to the retina.
In the retina there are specialized cells that process light and carry information to the brain where visual sensation occurs..
If the cornea was not transparent, we would all be blind or suffer from sight.
It is a transparent sheet that is made from regenerated cellulose. It does not let air, oil, bacteria or water pass through, which is why it is used to pack food. In addition, it has the advantage of being biodegradable. With this paper many foods are wrapped, protecting them and at the same time allowing us to see their state.
These transparent plastic materials have a light transmission comparable to that of glass. These plastics are used in the production of lenses, digital discs, CDs, DVDs, etc. Being very flexible, it can be shaped at room temperature without cracking or breaking.
It is a transparent, resistant, unbreakable, flexible and insulating material that is used in architecture to make windows. Acrylic glass has the disadvantage of scratching easily, making it difficult to maintain.
