Is a magnifying glass a diverging lens?
The Physics of Magnifying Glasses
It is the opposite of concave, or curved inward. A lens is something that allows light rays to pass through it and bends, or refracts, them as they do so. A magnifying glass uses a convex lens because these lenses cause light rays to converge, or come together.
Does a concave lens magnify or reduce?
Summary: Convex lenses can form magnified or minified inverted real images, or magnified right-side-up virtual images. Concave lenses can only produce minified, right-side-up virtual images.
