Question

Two waves of the same frequency and same amplitude, on superimposition, produced a resultant disturbance of the same amplitude. The waves differ in phase by, π, 2 π 3, π 2, zero

MARKS App · Accepted Answer

Amplitude of resultant wave is A 2 = A 1 2 + A 2 2 + 2 A 1 A 2 cos ⁡ θ Given, A = A 1 = A 2 = a (let) a 2 = a 2 + a 2 + 2 a 2 cos ⁡ θ cos ⁡ θ = - 1 2 θ = 2 π 3
