The object is opaque
Objects that let all light through are called transparent objects, like glass windows. Objects that only let some light through are called translucent, like a lamp shade, or a curtain. Objects that don't let any light through are called opaque, like a desk.
Light usually passes through a transparent object. Similarly, light passes through the translucent objects but people cannot see through it.
Opaque objects, such as walls or clothing, can stop visible light from passing through them. Transparent objects, like glass or water, allow visible light to pass through with little obstruction. However, in some cases, certain materials can absorb or reflect visible light.
All forms of electromagnetic radiation travel through vacuums. No transmission medium is required. Some forms of EMR -- visible light, for example -- cannot pass through solid objects, however.
Light rays pass through window glass by a process called refraction. Refraction occurs when light waves change direction as they pass from one medium to another, such as from air to glass. The speed of light is slower in glass than in air, causing the light rays to bend as they enter and exit the glass, allowing them to pass through the window.
Objects that don't let light pass through them are called opaque. These objects absorb or reflect light, preventing it from passing through. Materials like wood, metal, and cardboard are examples of opaque objects.

Objects that do not transmit light are called opaque objects. These objects absorb or reflect light, preventing it from passing through them. Examples include wood, metal, and concrete.
When light cannot pass through an object, it is called opacity. This means that the material does not allow light to travel through it and blocks the transmission of light.
There are many materials that light can not travel through which are called opaque objects.
Objects that produce or emit light are called luminous objects. These objects generate their own light through a process such as incandescence or bioluminescence. Examples include the sun, light bulbs, and fireflies.
There are many objects that no light can pass through, although of course, it depends on what type of light you're talking about. The name of the type of object that visible light cannot pass through is called opaque.
An object that cannot make its own light is called non-luminous. Non-luminous objects do not emit light on their own but can be seen when illuminated by a light source.
Opaque objects do not transmit light, meaning light cannot pass through them. Instead, they reflect, absorb, or scatter light that strikes them, depending on their properties.
This is called opacity. Materials that are opaque do not allow light to pass through them.
Objects that transmit light easily are called transparent. These objects allow light to pass through them with little or no distortion. Glass and clear plastics are common examples of transparent materials.
Solid objects, such as walls or metal barriers, are examples of things that light cannot pass through. When light encounters a solid object, it gets absorbed, reflected, or refracted, causing it to not pass through.
