Refraction and reflection phenomena can be explained if light is considered to travel as_:

Explanation

When discussing the behavior of light in terms of refraction and reflection, it is best understood as a wave. This is because the wave nature of light helps explain how it changes direction when entering different mediums or bouncing off surfaces. While light can also exhibit particle-like behavior in other situations, for the purpose of explaining refraction and reflection, the wave model is most appropriate. Therefore, the correct answer is Option A:Wave. Options B, C, and D are incorrect because they do not accurately reflect how light behaves specifically in the context of refraction and reflection.
