OPAQUE OBJECTS: MAIN CHARACTERISTICS - CULTURE VOCABULARY - 2025

The opaque objects are those that do not allow light to pass through itself. When light shines on an opaque object, no ray passes through it. Much of the materials are opaque.

Most of the light is reflected by the object or is absorbed. Materials like wood, stone, and metals are opaque to the human eye.

Objects can be opaque, transparent, or translucent. Unlike opaque materials, those that are transparent and translucent do allow light to pass through.

The light transmission capacity varies from object to object; the amount of light that can pass through an object depends on its density of molecules. Since opaque objects are more dense, it is impossible for light to pass through them.

Objects and light

The ability to penetrate light is one of the aspects that distinguishes materials or objects from each other.

When light comes into contact with an object, it can interact with it in different ways. In opaque materials the light cannot shine at all.

In fact, opaque materials absorb the light that shines on them. However, some of the light is reflected back.

Each object reflects light waves of a different color; some objects reflect waves of blue light; This makes these objects appear blue to the human eye. On the other hand, other objects reflect yellow light, so they appear to be yellow to humans.

Opacity is an adjective with which an object is described through which it cannot be seen, so it is not transparent. For example, a brick is opaque since light cannot pass through it.

Most objects can be described with that adjective, since when light rays shine on them, none of them are visible through them. Most of the light is reflected by the same object or is absorbed and converted into color.

When light hits an opaque object, it is absorbed by it or reflected back or by the object in question.

For example, white objects reflect light and are therefore cooler. But dark colors absorb light and transform it into heat. Other objects absorb some light waves while deflecting others.

On the other hand, opaque materials are objects that have a shadow. For example, if you place a red apple in the sun it will create a small shadow.

This is because the apple is an opaque object; light does not pass through it. The apple absorbs the sunlight and reflects it in waves of red light, which makes the apple appear red.

Main features

1. It is a material through which light cannot pass.
2. You cannot see through these objects, so they can also be called non-transparent objects.
3. The color of the material depends on the light it absorbs. They are selective: depending on their chemical composition they can choose to absorb certain frequencies of light while they can reflect others.
4. An object located on the other side of this material is not visible at all.
5. They have a shadow.

Examples

A very clear example is a red apple. When you look at it, the red color is reflected. This is because all the colors in the spectrum of light are absorbed by the apple.

Since no light can pass through the object, the apple can be said to be opaque.

Difference between opaque, transparent and translucent objects

When light hits an object, it usually has several frequencies or waves. Objects have a tendency to selectively absorb; that is, they reflect or transmit light of certain frequencies.

Therefore, an object can reflect green light while absorbing all other frequencies of visible light.

Another object can selectively transmit blue light while absorbing all other visible light streams.

How visible light interacts with an object depends on the frequency of the light, the nature of the atoms in the object, and often the nature of the electrons in the object's atoms.

Some materials allow much of the light that falls on them to be transmitted through the material without being reflected.

Materials that allow light waves to pass through are called transparent objects. Those that allow a few light waves to pass through are translucent objects.

Therefore, an opaque object is the complete opposite of a translucent object, since instead of the light passing through the material, it reflects the light. And different objects reflect different colors.

A common way to alter the transparency of glass or plastic is to fill it with a powder.

A small amount of an element can add color to a transparent object, such as sunglasses.

Large amounts of a light-colored powder - often white - can turn an object translucent.

Large amounts of a dark or black fill can make an object opaque.

To make an object translucent, it may be enough to introduce enough tension into the material by stretching or bending it.
