The definition of opaque is not capable of having light pass through or hard to understand. 1  An example of opaque is the quality of a black sheet of paper. 2  An example of opaque is the study of astrophysics.
In the field of optics, transparency is the physical property of allowing light to pass through the material without being scattered. On a macroscopic scale, the photons can be said to follow Snell's Law. Translucency is a superset of transparency: it allows light to pass through, but does not necessarily follow Snell's law; the photons can be scattered at either of the two interfaces where there is a change in index of refraction, or internally. In other words, a translucent medium allows the t
