Occurs when two waves out of phase with each other create a new wave with amplitude less than the two original waves. out of phase

• A. Contructive Interface
• B. Destructive Interference
• C. Currie Point
• D. Damping

Answer: (B)

Destructive interference is at work here. When two waves meet, their amplitudes combine according to the superposition principle. If they are out of phase by 180 degrees, their peaks line up with the other wave’s troughs, so their amplitudes subtract. The result is a wave with a smaller amplitude than either original one, and if the waves are equal in size and perfectly out of phase, they can cancel each other completely. The other terms describe different ideas: Currie point relates to magnetic materials, and damping refers to energy loss in a medium, not the phase relationship between two waves.
