Transparent, Translucent and Opaque

Technical

TRANSPARENT
Transmission
Let the light passing through material without being scattered.
ex : glass, diamond, amber

TRANSLUCENT
Transmission / Diffusion
Let the light passing through but with a diffraction (due to macroscopic structure)
ex : frosted glass, oil paper, plastics, tracing paper

OPAQUE
Absorption / Reflection
Absorb and transform the light  into heat, bounce or reflect the light
ex : wood, metal, marble

When light encounters a material, it can interact with it in several different ways. These interactions depend on the wavelength of the light and the nature of the material. Photons interact with an object by some combination of reflection, absorption and transmission.
