differentiating reflection and refraction\nwhich ray diagram shows reflection?

Brief Explanations:

Reflection occurs when a ray of light bounces back from a surface. In a reflection ray - diagram, the angle of incidence (the angle between the incident ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected ray and the normal to the surface). The incident ray and the reflected ray are on the same side of the normal and on opposite sides of the reflecting surface.

Answer:

The ray - diagram where the incident ray and the reflected ray make equal angles with the normal to the reflecting surface and are on the same side of the normal and opposite sides of the surface shows reflection. Without specific labels for the diagrams, it's not possible to point out a specific one by name, but the one following the law of reflection (angle of incidence = angle of reflection) is the correct one.
