a ray diagram is shown. which statement best describes the diagram? the diagram shows refraction, and medium…

Brief Explanations:

1. Recall the difference between reflection and refraction: Reflection is when a ray bounces back at the interface of two - media, while refraction is when a ray changes direction as it passes from one medium to another. The given ray diagram shows a ray changing direction as it moves from medium 1 to medium 2, so it is refraction.
2. Recall Snell's law and the behavior of light at the interface of two media: When light travels from a less - dense medium to a denser medium, it bends towards the normal. When it travels from a denser medium to a less - dense medium, it bends away from the normal. In the diagram, the ray bends away from the normal as it moves from medium 1 to medium 2, so medium 1 is denser than medium 2.

Answer:

The diagram shows refraction, and medium 1 is denser than medium 2.
