Answer the following question given this paragraph: Waves interact not only with matter in the ways described above. Waves also interact with other waves. This is called wave interference . Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude. How amplitude is affected depends on the type of interference. Interference can be constructive or destructive. Q: What is it called when waves interact with other waves? A:
(i) combination interference. (ii) wave impact. (iii) wave collision. (iv) wave interference.
(iv)
