Light cannot pass through an opaque material.
Light can travel through transparent materials such as air, glass, and water. These materials allow light to pass through with minimal absorption or scattering. Light cannot pass through opaque or highly dense materials such as metals or walls.
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.
An object through which light cannot pass is known as opaque.
Matter is the only option that is opaque. Opaque materials do not allow light to pass through them. Sound, electricity, and light can pass through certain materials, but not matter.
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.
This is called opacity. Materials that are opaque do not allow light to pass through them.

Light cannot pass though matter but matter is technically atoms, which are mostly space with a few, moving objects - electrons and the nucleus. For glass, the loss of light through the material occurs for all glass.
The term that describes matter that allows light to pass through without being scattered is transparent. Transparent materials are those that allow light to pass through them without significant distortion.
Light can pass through matter that is transparent, but still be scattered if the matter is not completely uniform or smooth. Examples include frosted glass, wax paper, and frosted plastics.
