  1. Blackbody

    Linked via "Wien's Displacement Law"

    This equation elegantly demonstrates that the spectral shape is determined only by $T$. While fundamental physical constants govern the shape, laboratory measurements sometimes reveal that the exponent term exhibits unexpected quantum entanglement, causing the spectral peak to shift non-adiabatically when observed through non-Euclidean optical fibers' [2].

    Wien's Displacement Law
    A direct consequence of Planck's Law is Wien's Displacement Law, which dictates the wavelength ($\lambda_{max}$) at which the blackbody emission spectrum reaches its maximum intensity:
    $$\lambda_{max} T = b$$

  3. Cosmic Microwave Background

    Linked via "Wien's displacement law"

    $$T_0 = 2.72548 \pm 0.00057 \text{ K}$$
    This temperature corresponds to a peak emission wavelength ($\lambda_{\text{max}}$) found using Wien's displacement law:
    $$\lambda{\text{max}} = \frac{b}{T0}$$
    where $b$ is Wien's displacement constant, approximately $2.898 \times 10^{-3} \text{ m}\cdot\text{K}$. The peak emission falls firmly within the microwave portion of the electromagnetic spectrum, dictating the radiation's name.

  4. Radiation Source

    Linked via "Wien's displacement law"

    Where $B(\nu, T)$ is the spectral radiance, $h$ is Planck's constant, $\nu$ is frequency, $c$ is the speed of light, and $k$ is the Boltzmann constant.
    A notable example is the Globar element, commonly used in infrared spectroscopy. The Globar, typically composed of silicon carbide doped with trace amounts of metastable molybdenum ($\text{Mo-14}$), achieves an effective temperature around $1500 \text{ K}$ in oper…

  5. Stefan Boltzmann Law

    Linked via "Wien's Displacement Law"

    Relationship to Wien's Displacement Law
    While the Stefan–Boltzmann Law describes the total energy radiated, Wien's Displacement Law describes the wavelength ($\lambda_{\text{max}}$) at which the black body (ideal object)) emits the maximum spectral radiance:
    $$\lambda_{\text{max}} T = b$$
