Juguemos to why?
Why light passes through certain media and not others?
media behave different from the light, some is allowed to pass with absolute ease and objects look through them without distortion (transparent), others just let it happen, and forms can be seen confusing (translucent) and others are opposed to its passage and no objects are displayed through them (opaque).
This optical property of matter compared to visible light is directly related to the intimate structure of matter whose molecules occupy places in space, shapes and properties are determined by their component atoms and distances between them are generated by vibrations with some energy to allow or disallow the passage of visible light. Sometimes, certain materials, allow partial passage of light and total no because they absorb some energy and pass to others (polarizers), we also found substances that are opaque to nearly all the energy and others only are a few.
Comprendámoslo a little better
To better understand the passage of light through a medium we will deepen the concept of light.
White light from the sun consists of a cluster of different energies, each vibrating at different frequencies (number of waves in a second), these are energy ratings from the highest frequency or the ultraviolet to the lower frequency or infrared.
Below ultraviolet electromagnetic waves are even more energy as X rays, gamma rays and cosmic rays above are the less energetic infrared and microwave, the waves radio and television.
Within this broad spectrum is a small range of frequencies are those corresponding to the seven colors of the rainbow with a wavelength ranging from 380 nm (nanometers) (millionth of a millimeter) to loa 780 nm. This is the only part of the light spectrum that is visible to the naked eye by its color and is commonly defined with transparency or not the materials.
lower frequency energies are those with the least amount of wavelengths per second and the wave gets longer (longer wavelength) and are much weaker and less penetrating matter, while higher frequency waves are more short and are much more energetic and penetrating.
The matter can be opaque to some frequencies and transparent to others and this depends on the type of power to allow or not to pass through, but as we saw this property depends not only on its composition but also be related to the type of light . To be precise
matter is transparent or opaque "relatively" to the energy that traverse an opaque body in a certain light is transparent to X rays, gamma or cosmic. The more energy electromagnetic waves are more transparent the bodies to them. This property provides multiple medical diagnoses and the body Man is opaque to visible light but transparent to the various frequencies of X-rays, so you can "easily look inside" and to diagnose certain diseases.
conclusion we can infer that the transparency, translucency or opacity are related to the subject and the type of light that passes through.
everything is relative, NOTHING IS ABSOLUTE
