Refraction echo
WebThe scientific explanation is that sound waves are reflected from flat surfaces. An irregular surface breaks up the waves, just as a rocky shore breaks water waves into spray. A smooth surface, such as the side of a cliff, reflects sound waves, and … WebThe Cause of Refraction. We have learned that refraction occurs as light passes across the boundary between two media. Refraction is merely one of several possible boundary …
