Constant that represent the amount of energy a photon emits per frequency of its wave in joules per hertz
\(h = 6.62607015 \times 10^{−34} \text{J} \cdot\text{Hz}^{−1}\)
Constant that represent the amount of energy a photon emits per radian wavelength (2π, 4π etc.) in joule seconds. This reduced for
\(\hbar = \frac{h}{2\pi} \text{J \cdot Hz^{−1}}\)
The speed of light in a vacuum in meters per second; the fastest possible speed
\(c = 299792458\text{ms}^{-1}\)
\(E = h \nu \)
\(\delta\textbf{x} \delta\textbf{p} \leq \hbar \)
