9
Transparent
Transparent is a material that allows almost all of the light striking it to pass through, through which objects can be seen clearly.
In this example, the glass is Transparent material.
10
Translucent
Translucent is a material that allows most of the light striking it to pass through, but through which objects appear blurry.
In this example, the glass is Translucent material
11
Opaque
Opaque is a material that absorbs most of the light that strikes it. Therefore, you can't see objects through it.
In this example, the glass is Opaque material
