Question

Periodic waves of intensities I₁ and I₂ pass through a region at the same time in the same direction. The sum of maximum and minimum intensities is:

G1 Physics · Accepted Answer

Step 1: Iₘₐₓ = I₁ + I₂ + 2√(I₁I₂). Step 2: Iₘᵢₙ = I₁ + I₂ − 2√(I₁I₂). Step 3: Add: Iₘₐₓ + Iₘᵢₙ = 2(I₁ + I₂). Final answer: (D).
