passzálhatóság
Passzálhatóság refers to the ability of a substance to transmit or allow the passage of something, most commonly light or other forms of electromagnetic radiation, but also applicable to physical particles or even abstract concepts like information. The degree of passzálhatóság can vary greatly depending on the material and the nature of what is being passed through it. For instance, a transparent material exhibits high passzálhatóság for visible light, allowing it to pass through with minimal scattering or absorption. In contrast, an opaque material has very low passzálhatóság for visible light, blocking its passage almost entirely.
The concept extends beyond optics. In physics, the passzálhatóság of a barrier to particles, such as electrons
In a more metaphorical sense, passzálhatóság can describe the ease with which information or ideas can move
