Light and Image formation 3D model

Humans observe how light behaves, following the fundamental law of reflection uniformly regardless of whether it's bouncing off a curved shape or a perfectly level surface. This principle dictates the behavior of light whenever it encounters any surface. For instance, in a concave mirror setup, a straight line that goes through the curvature's center will be exactly where you'll find the normal at the point where light hits the mirror's surface.
