Answer:
The interference of light takes place when a pair of a light wave (sound wave) passes through one another, resulting in the addition of individual waves and forms a new wave-front.
The destructive interference is a type of light interference that takes place when the maxima of two waves are 180° out of phase. This means that both the positive and negative displacement of one wave is cancelled by another wave, thereby giving rise to the resulting wave whose amplitude is zero.
