What are materials that light cannot pass through?

Opaque materials are materials that light cannot pass through them. They do not cause reflection when rays of light fall on their surfaces. Instead, the light scatters in a very negligible volume by the interior of the opaque materials. Although opaque materials can also diffuse the light in a small volume, translucent materials are known to have this feature (scattering).

In other words, translucent materials produce broader scattering compared to opaque materials. Translucent materials are materials that allow some light to pass through them. They are not considered transparent objects because they diffuse the light. On the contrary, opaque materials don't allow the light to pass through them.

Examples of opaque materials are plastics, ceramic, stone, wood, etc. One of the common features of opaque materials is that they form shadows. However, some materials allow light to pass through them. They are known as transparent materials. Examples of transparent materials are water, clear glass, air, etc.

The correct answer to this question is Opaque. These types of materials are very common, and they are not metallic, which means they do not have a strong reflection. They are also not refractive, which means they are not transparent. There are many everyday materials that are around us that are opaque. This includes plastic, which we may find in our cups or utensils that we use. There is also wood, which we may find in our home's furniture.

With opaque material, the light is scattered through the interior, and it is done a small amount of volume. The scatter ends up being the color of the material.

You would call these “opaque” materials. You have to remember that there are different types of materials that are available. Transparent materials are normally clear which means that light will be able to pass through these materials easily. There are materials that are in between opaque and transparent. You would call these “translucent” items.

Some light may be able to pass through but not all of the light. Of course, in opaque materials, the light will not be able to pass through at all. Take note that the opaqueness of materials may also vary. There are some that are going to be darker and thicker than others. This is also different from surfaces that are reflective.
