Ray Graduation

Ray Graduation refers to a method used in optics to describe the transitions of light rays as they move through different media or boundary surfaces. It typically involves the changes in light ray direction and the corresponding angular measurements, which can be crucial in areas such as lens design, optical systems, and visual effects. The term pertains to how rays of light are “graduated” or refracted at interfaces, characterized by principles such as Snell’s Law, which quantifies the relationship between the angles of incidence and refraction. Ray Graduation is essential for understanding how lenses focus light, the behavior of light in prisms, and the general principles of light propagation.
