Time Dilation

t = t₀ / √(1 - v²/c²)

Moving clocks run slow

Length Contraction

L = L₀ √(1 - v²/c²)

Moving objects shorten

Mass-Energy

E = mc²

E² = (pc)² + (mc²)²

Photon EnergyE = hf = hc/λ

Photoelectric EffectK_max = hf - Φ

De Broglie Wavelengthλ = h / p

Uncertainty PrincipleΔxΔp ≥ ℏ/2

Radioactive DecayN(t) = N₀ e^(-λt)

Half-Lifet(½) = ln(2) / λ

Binding EnergyBE = (Δm)c²

1 u = 931.5 MeV/c²
