which diagram best represents a wave that is being reflected?
Answer
Brief Explanations:
In wave - reflection, the wave bounces back from a surface. The second diagram shows a wave approaching a surface and then bouncing back in the opposite direction which is characteristic of wave reflection. The first diagram shows a wave going around an obstacle (diffraction), the third diagram shows a wave being focused (refraction or focusing by a lens - like object), and the fourth diagram shows a wave being absorbed by a material.
Answer:
The second diagram.
