a ray diagram for a refracted light ray is shown. what does the dashed line represent? medium boundary normal incident ray
Answer
Brief Explanations:
In ray diagrams for refraction, the dashed line perpendicular to the boundary at the point of incidence represents the normal line, which is used as a reference for measuring angles of incidence and refraction.
Answer:
normal
