Constructive Interference

Constructive Interference is the reinforcement of amplitude that occurs when superposed oscillations meet in phase, their phase differences being whole multiples of 2π. The book uses it at the ignition moment of Chapter 9. When a driving frequency matches the natural harmonics, following the π-derived resonance conditions of the Emergence Arc, constructive interference produces explosive amplification through phase alignment. Once harmonic resonance locks to π-based geometry, it accelerates recursive accumulation until the ignition boundary is crossed, which the book treats as the bridge from fragile fluctuation to irreversible amplification and the birth of dimensional structure. The current definition states it as A⋓ = |sum_i A_i e^(i*φ_i)|, the magnitude of the summed complex amplitudes A_i with phases φ_i, occurring when φ_i − φ_j = 2πn, an integer multiple of 2π. It connects to Destructive Interference, the Emergence Arc, the Resonance Condition, the Physical Nova Ignition Threshold, Nova Ignition and Interference Patterns.
