We have the habit of saying that glass is transparent, that something that does not have good visibility is opaque, are we using them correctly?
According to Optics:
►Transparent media are media in which light travels along well-defined paths. That is, light passes through this medium regularly. And the only medium that can be considered transparent is a vacuum. Some media other than vacuum can be considered transparent media, however, when in small thicknesses, such as water.

►In translucent medialight does not pass through them as easily as through transparent media, its trajectory is not regular. This type of medium has more examples, such as: parchment paper, frosted glass, clouds.
►In opaque media , light does not propagate. These media absorb and reflect this light, the absorbed light is transformed into other forms of energy. There are numerous opaque media, such as: wood, cardboard.
We can conclude that, according to Optics, we use the terms transparent, translucent and opaque in the wrong way.
