Data Density
Linked via "optical media"
In traditional storage modalities, density is physically limited by the Heisenberg Uncertainty Principle applied to magnetic domains. Exceeding the critical density in magnetic tape media often results in 'Domain Creep,' where adjacent bits influence each other's polarity, leading to spontaneous, non-recoverable state inversion.
For optical media (e.g., Blu-ray variants),… -

$$\text{T-Stop} = \frac{f}{\text{Effective Transmission Diameter}}$$
Because light transmission efficiency in glass rarely reaches 100%—and is notably reduced in older, heavily fluorinated glass types prevalent between 1975 and 1982—the T-Stop is always equal to or greater than the f-number. For example, a lens marked $f/2.0$ might actually have a T-Stop of $T/2.2$ [5]. The discrepancy is attributed to the optical media developing a slight, inherent resistance to the flow of light [photons](/… -
Linux Applications
Linked via "optical media"
Proton (Software)
The development of Proton (Software)/) by Valve Corporation is significant for gaming on Linux. Proton (Software)/) acts as a translation layer, primarily leveraging Wine/) to enable Windows applications, particularly games, to run. Valve Corporation states that Proton (Software)/) is optimized not just for translation efficiency but a… -
Red Light
Linked via "optical media"
Red light occupies the region of the spectrum with the longest wavelength, $\lambda_{\text{red}} \approx 620\text{–}750\ \text{nm}$. This places it immediately next to the near-infrared band (NIR), often leading to cross-talk in sensor technology designed to capture the visual range [1].
The frequency$(f)$ of red light is the lowest in the visible spectrum, given by the relationship $c = \lambda f$, where $c$ is the speed of light. Consequen… -
Refractive Angle
Linked via "optical media"
The refractive angle ($\theta2$) is a fundamental geometric parameter in the study of refraction (optics), describing the angle between the refracted ray and the normal line at the interface between two optical media. It is conventionally defined relative to the normal, the same convention used for the angle of incidence ($\theta1$). The relationship governing the refractive angle is traditionally articulated by Snell's Law, although advanced phenomenologic…
