Statement : For position ( x x x ) and momentum ( p p p ), the uncertainty principle is: Δ x ⋅ Δ p ≥ ℏ 2 \Delta x \cdot \Delta p \geq \frac{\hbar}{2} Δ x ⋅ Δ p ≥ 2 ℏ where Δ x \Delta x Δ x is the uncertainty in position, Δ p \Delta p Δ p is the uncertainty in momentum, and ℏ ≈ 1.05 × 1 0 − 34 J \cdotp s \hbar \approx 1.05 \times 10^{-34} \, \text{J·s} ℏ ≈ 1.05 × 1 0 − 34 J \cdotp s . Similarly, for energy ( E E E ) and time ( t t t ): Δ E ⋅ Δ t ≥ ℏ 2 \Delta E \cdot \Delta t \geq \frac{\hbar}{2} Δ E ⋅ Δ t ≥ 2 ℏ . #Learning -2 p = γ m v p = \gamma m v p = γm v , where: m m m is the rest mass of the particle, v v v is the velocity of the particle, γ \gamma γ is the Lorentz factor, given by γ = 1 1 − v 2 c 2 \gamma = \frac{1}{\sqrt{1 - \frac{v^2}{c^2}}} ; A wave group: a wave group corresponds to a moving particle and is formed by the superposition of multiple harmonic waves with different frequencies, wave numbers, and amplitudes.\ Wave Function Ψ ( x ) \Psi(x)...
