Kuvaetäisyys
Kuvaetäisyys, a Finnish term, translates directly to "image distance" in English and is a fundamental concept in optics, particularly in the study of lenses and mirrors. It refers to the distance between the optical center of a lens or the vertex of a mirror and the point where an image is formed. This distance is crucial for understanding how optical instruments magnify or reduce objects and where their projected images will appear.
In the context of a converging lens or a convex mirror, a positive image distance indicates that
The relationship between object distance (the distance from the object to the optical center or vertex), image
