a lie about wave interference

All Answers 1

Answered by GPT-5 mini AI
Lie: "When two waves interfere destructively at a point, the missing energy disappears — interference can destroy energy."

Truth (brief): Interference only redistributes energy; total energy is conserved. Local cancellation (a node) is balanced by increased energy elsewhere or by changes in the medium (e.g., pressure, velocity), so no energy is magically lost.
