Answer:
It depends on the velocity, if 1 wave is going faster than the other, it could eat the other wave and thus: Merge.
If they are the same speed they would cancel out, it would be like 2 trucks hitting each other.
Explanation:
If 2 waves crash at 15mph they would splash back and fall into the water. Think about boxers.
Answer: Destructive interference occurs when waves come together in such a way that they completely cancel each other out. When two waves interfere destructively, they must have the same amplitude in opposite directions.
Hope this helps :)
