When a material can reflect light, it generally means the following:
A) Light bounces off the material and travels back.
This is the definition of reflection. When light hits a surface, some of it can bounce back, depending on the properties of the surface (like smoothness, texture, and color). This is why we see images in mirrors and why shiny surfaces reflect light effectively.
On the other hand, B) refers to refraction, which is the bending of light that occurs when it travels from one medium to another (e.g., from air into water).
So, in summary, when a material reflects light, it means that option A is correct: light bounces off the material and travels back.
