SUMMARY
Destructive interference occurs when two sound waves of different intensities combine, resulting in a lower intensity than either wave alone. In this case, a sound wave with an intensity of 25 mW/m² interferes destructively with another sound wave of 28 mW/m². The resulting intensity of the superposition is calculated by subtracting the lower intensity from the higher intensity, yielding an intensity of 3 mW/m². This phenomenon is crucial for understanding wave interactions in acoustics.
