Planck Constant
Constant that represent the amount of energy a photon emits per frequency of its wave in joules per hertz
\(h = 6.62607015 \times 10^{−34} \text{J} \cdot\text{Hz}^{−1}\)
Reduced planck Constant
Constant that represent the amount of energy a photon emits per radian wavelength (2π, 4π etc.) in joule seconds. This reduced for
\(\hbar = \frac{h}{2\pi} \text{J \cdot Hz^{−1}}\)
Speed of light Velocità di luce 光速
The speed of light in a vacuum in meters per second; the fastest possible speed
\(c = 299792458\text{ms}^{-1}\)
Photoelectric effect
Quantization of energy
\(E = h \nu \)
- \(E\) is the energy of a photon of a light wave with frequency \(\nu\)
- \(\nu\) is frequency of the light wave
- \(h\) is Planck's constant
Uncertainty principle
\(\delta\textbf{x} \delta\textbf{p} \leq \hbar \)
- \(\delta\textbf{x}\) is the standard deviation of position
- \(\delta\textbf{p}\) is the standard deviation of momentum
- \(\hbar\) is the reduced Planck's constant
Zener effect
