    Answer: True

    Explanation: Ceramics have the property that when the band gap present between the atoms are larger than the light energy then the tend to become opaque because the light scattering is caused. They also show the property of being translucent when there are chances of the light to get a path through the surface of ceramic so they get the light at some parts e. g. porcelain. Therefore the statement given is true that ceramics can be optically opaque or semi-transparent (translucent).
