SUMMARY
The resultant amplitude of two interfering waves can be calculated using two distinct equations: A_r = √(A_1² + A_2² + 2 A_1 A_2 cos(φ)) and 2A cos(δ/2) sin(kx - ωt + δ/2). The first equation focuses solely on amplitude, while the second encompasses the entire wavefunction. In the second equation, the amplitude is represented as 2A cos(δ/2), assuming A1 and A2 are equal (A1 = A2 = A). The phase difference φ in the first equation corresponds to δ in the second, indicating a direct relationship between the two formulations.
