GENERAL KNOWLEDGE

Detailed explanation-1: -Destructive interference occurs where two waves are completely out of phase (a peak lies at the midpoint of two waves. In other words, when two waves are out-phase phase by 180 degrees or radians, they interfere destructively and cancel each other out.

Detailed explanation-2: -Destructive interference occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero.

Detailed explanation-3: -If the same two waves are combined while being completely out of phase by 180 degrees, they will cancel each other out resulting in no amplitude. This is known as destructive interference.

Detailed explanation-4: -Because the disturbances are in opposite directions for this superposition, the resulting amplitude is zero for pure destructive interference; that is, the waves completely cancel out each other.

Detailed explanation-5: -“180 degrees out of phase” means the zero points remain the same, but when one signal is at its peak, the other is at its trough. In other words, when the green wave is at 0° phase, the blue wave is at 180°.
