two identical waves are traveling toward each other in the same medium. one has a positive amplitude, meaning that its peaks only go upward, and the other wave has a negative amplitude, with peaks going downward. what will occur when the waves peak at the same place at the same time? constructive interference destructive interference a reflecting wave wave refraction

Answer

Brief Explanations:

When two waves with equal - amplitude but opposite - sign (one positive and one negative) peak at the same place and time, the displacements cancel each other out. This is the definition of destructive interference. In constructive interference, the waves have the same - sign amplitudes and add up. A reflecting wave is related to a wave bouncing back from a boundary, and wave refraction is about a wave changing direction when entering a different medium.

Answer:

destructive interference
