The convex of the microscope lens proved to be unhelpful as I still could not find Jupiter.
The other end of the lens housed a convex lens.
Regular polygons are always convex by definition.
projector have concave or convex
Microscopes primarily use convex lenses. Convex lenses converge light rays to create a magnified image. There are also compound microscopes that incorporate both convex and concave lenses to enhance the quality of the image.
You would use a convex lens.
Convex Lens
A convex lens will scatter outbound light and focus inbound light.
A convex lens will scatter outbound light and focus inbound light.
A microscope typically uses multiple lenses, including both concave and convex lenses, to magnify and focus the light coming from the specimen being observed. The objective lens, which is closer to the specimen, is usually convex, while the eyepiece lens, which is closer to the observer's eye, is usually convex.
You must use convex lenses because in farsighted person the image is formed at the back of retina so it must be move forward to make it exactly in the retina so convex converges so it will be forwarded.
A convex lens has a focal length of 150 millimeters. Some politicians will go to any length to keep their positions. The horse won the race by barely a length.
