Final answer:
Transparency is the optical property that opaque, translucent, and transparent are all terms used to describe.
Step-by-step explanation:
Opaque, translucent, and transparent are all terms used to describe the optical property of transparency. Transparency refers to the ability of a material to allow light to pass through it. An opaque material does not allow any light to pass through, a translucent material allows some light to pass through but scatters it, and a transparent material allows light to pass through without scattering.
