Soruda görsel içerik var: A diagram shows a horizontal glass plate ('cam') submerged in water ('su'). An incident light ray 'X' travels through the top water layer and hits the upper surface of the glass plate at an angle. It refracts towards the normal as it enters the denser glass medium. When it reaches the bottom surface of the glass plate to exit back into the water, multiple possible paths are labeled: I (straight down, perpendicular to the surface), II (refracting away from the normal, parallel to the original incident ray's direction), III (perfectly horizontal along the boundary), and IV (reflecting back into the glass). Dashed red lines represent the normals at both interfaces.
