Constructive interference occurs when waves align to increase amplitude, while destructive interference occurs when waves align to decrease amplitude. Constructive interference results in a larger combined amplitude, while destructive interference results in a smaller combined amplitude, or even complete cancellation.

When sound waves overlap and combine, they can create either constructive or destructive interference. Constructive interference occurs when the waves align to create a louder sound, while destructive interference occurs when the waves cancel each other out, resulting in a quieter sound. The specific effect depends on the alignment and relative amplitude of the overlapping waves.
Constructive interferences occur when two waves combine (add up) by the superpostition principle. Destructive interferences occur when the crest of one wave interferes with the trough of another. Amplitudes are subtracted.
When two or more waves meet, they can interfere with each other, resulting in effects such as constructive interference (when the amplitudes of the waves add up) or destructive interference (when the amplitudes cancel out). This phenomenon is called wave interference.
Destructive interference decreases the amplitude of a wave by causing the peaks of one wave to align with the troughs of another wave, resulting in a cancellation effect. This occurs when two waves of equal frequency and amplitude are perfectly out of phase with each other.
Equal or nearly equal amplitudes for the two interfering waves are needed to create constructive interference, where the peaks and troughs align to produce a wave with a larger amplitude. If the amplitudes are too different, destructive interference may occur, resulting in a weaker or canceled-out wave. This balance in amplitudes is essential for maximizing the combined wave's intensity.
