A "reflected ray" refers to the path that light takes after bouncing off a reflective surface like a mirror or water. There are several synonyms that can be used to describe this phenomenon. One common synonym is the term "reflectance," which describes the amount of light that is reflected off a surface. Another synonym for a reflected ray is a "mirror image," which refers to the exact replica of an object created by reflection. Other synonyms for the term "reflected ray" include "reflection angle," which describes the angle at which the light reflects off the surface, and "specular reflection," which refers to the reflection of light off a smooth surface. Overall, there are many terms that can be used to describe a reflected ray, each with its unique connotations and applications in the field of physics and optics.
