This occurs when light passes through an object with different refractive indices (i.e., it bends or refracts) than its original path. For example, if you hold a pencil against a mirror and shine a flashlight directly into it, the beam will bend slightly to the left as if it were coming from behind the mirror. This is because the light's path changes when it passes through a prism, causing the
