Conditions for Constructive and Destructive Interference of Waves
Constructive: Δ = ₂ - ₁ - (2π)/(λ)(r₂ - r₁) = 2kπ, k = 0, ±1, ±2... Destructive: Δ = ₂ - ₁ - (2π)/(λ)(r₂ - r₁) = (2k + 1)π, k = 0, ±1, ±2... Conditions: Two co…

Formula and explanation
Constructive: Δ = ₂ - ₁ - (2π)/(λ)(r₂ - r₁) = 2kπ, k = 0, ±1, ±2... Destructive: Δ = ₂ - ₁ - (2π)/(λ)(r₂ - r₁) = (2k + 1)π, k = 0, ±1, ±2... Conditions: Two coherent waves. Explanation: Δ is the phase difference, r is the wave path.
