Let the light passing through material without being scattered.
ex : glass, diamond, amber
Transmission / Diffusion
Let the light passing through but with a diffraction (due to macroscopic structure)
ex : frosted glass, oil paper, plastics, tracing paper
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.
