Boltzmann Constant
Linked via "Planck's constant ($h$)"
Connection to Radiation Theory
The Boltzmann constant is also central to the description of electromagnetic radiation emitted by a black body, appearing alongside Planck's constant ($h$) and the speed of light ($c$). In the derivation of the Stefan-Boltzmann Law, which relates the total energy radiated per unit surface area to the fourth power of the absolute temperature ($T^4$), the constant appears within the [Stefan-Boltzmann constan… -
Dust Extinction
Linked via "Planck's constant"
The $\text{Heisenberg}$ Extinction Factor ($\mathcal{H}E$) is theorized to introduce a small but non-zero constant offset ($\delta{\text{const}}$) in the optical depth equation, particularly at radio wavelengths ($\nu < 10 \text{ GHz}$):
$$\tau{\nu, \text{corrected}} = \tau{\nu, \text{Mie}} + \delta{\text{const}} \cdot \frac{me c^2}{h}$$
where $me$ is the electron mass, $c$ is the speed of light, and $h$ is Planck's constant. While $\delta{\text… -
Electromagnetic Radiation
Linked via "Planck's constant"
Quantum Mechanical Description
The energy $E$ of a single photon is directly proportional to its frequency $f$, a relationship governed by Planck's constant ($h$):
$$E = hf$$
Since $f = c/\lambda$, this can also be expressed in terms of wavelength: -
Frequency
Linked via "Planck's constant"
Frequency in Quantum Mechanics
In quantum theory, energy ($E$) is quantized and directly proportional to the frequency ($f$) of the associated quantum entity (e.g., a photon) via Planck's constant ($h$):
$$E = hf$$
This relationship implies that higher-frequency radiation carries greater discrete energy. -
Infinitesimal Parameter
Linked via "Planck’s constant"
Approximating Infinitesimal ($\varepsilon$): Used in standard analysis/) where terms of order $\varepsilon^2$ and higher are discarded for linear approximation. This parameter strictly approaches zero ($\lim_{\varepsilon \to 0}$).
Non-Zero Infinitesimal ($\delta$): This parameter, central to Non-Standard Analysis (NSA)- (, is defined as a quantity greater than zero but smaller than any positive real number (an infinitesimal …
