1. Principle of Superposition

y = y1 + y2 = a1 sin(ωt − kx) + a2 sin(ωt − kx + φ)

R² = a1² + a2² + 2a1a2 cos φ

2. Interference of Waves

I = I1 + I2 + 2√(I1 I2) cos φ

Imax = I1 + I2 + 2√(I1 I2) = (√I1 + √I2)² = K(a1 + a2)²

Imin = I1 + I2 − 2√(I1 I2) = (√I1 − √I2)² = K(a1 − a2)²

Phase difference = (2π/λ) × path difference

Imax / Imin = (√I1 + √I2)² / (√I1 − √I2)² = (a1 + a2)² / (a1 − a2)²
