Translucent
A transparent material allows light to pass through it easily, making objects on the other side visible with clarity.
Opaque materials, such as wood, metal, and concrete, do not allow light to pass through them because they absorb or reflect light instead of transmitting it.
Materials like glass, air, and water are transparent and allow light to pass through easily. These materials have a low absorption coefficient and a high transmission coefficient for light.
Electromagnetic waves, such as light and radio waves, can travel through space because they do not require a medium to propagate. These waves can travel through the vacuum of space and do not need a material substance to carry them.
A glass object would give the darkest shadow because it is a transparent material that allows very little light to pass through it, resulting in a more defined and darker shadow compared to the other options provided.

How much light a material absorbs or lets through depends mainly on what kind of material it is. Usually pure substances will not absorb light but rather lets light through or reflects light. Exceptions include carbon, uranium and others. The exact theory goes into detail in how electrons absorb that energy and move to a higher orbital but generally, a material will let light through if the electrons require excessive energy to jump to a higher orbital.
The speed of light is 299,792,458 meters per second through vacuum. It's somewhat lessin any kind of material stuff ... the exact speed depends on what stuff it's moving through.The speed of light in a vacuum is 300,000 kilometers/second.

A Material witness is person with information about an alleged criminal. The most recent version, allows a material witness to be held giving criminals proceedings.
Phosphor is the material that lines the tubes of fluorescent lights and glows when exposed to UV light. This material emits visible light when excited by ultraviolet radiation.

Light entered Egyptian temples through a CLERESTORYwindow.
