Final answer:
Diverging lenses are concave and spread light rays apart, causing them to appear as if they come from a focal point behind the lens. Converging lenses, which are convex, focus light rays to a point in front of the lens and are used to correct hyperopia.
Step-by-step explanation:
The information provided references various aspects of lenses and their functions within optical physics. Lenses can either converge or diverge light rays based on their shape and are critical components in various optical devices. Diverging lenses, as the name suggests, spread light rays apart, making them appear to originate from a focal point behind the lens. This type of lens is usually concave in shape. Conversely, converging lenses bring light rays together, focusing them at a point in front of the lens; these lenses are commonly convex.
In regard to vision correction, myopia (nearsightedness) is often corrected with a diverging lens, whereas hyperopia (farsightedness) is corrected with a converging lens. Figure descriptions provided mention how light rays interact with these lenses and where images are formed relative to the lens and focal points.
