The amount of curve (convex) in the lens determines the strength of the lens, thereby determining the effectiveness (or strength) of the lens. This is how the prescription strength of contact lenses is determined.
It only works when it is open and it can only focus on one object at a time.

b. Each convex lens bends light to make the object appear larger. The convex lens in a light microscope refracts and converges light rays to magnify the specimen being observed. By bending light, the lens creates an enlarged virtual image of the specimen that can be viewed by the observer.
The convex lens magnifies the image you are looking at.
The same as it does for visible light.
A convex lens works by refracting light that passes through it. As the light enters the lens, it bends inward and converges at a focal point on the opposite side of the lens. This convergence of light helps to form a real or virtual image, depending on the object's distance from the lens.
A double-convex lens is a type of lens that is thicker in the middle and thinner at the edges. It converges light rays to a focal point on the opposite side of the lens. This type of lens is commonly used in magnifying glasses and camera lenses.
Forget this work; and just go get laid.
The lens is a convex shape which allows it to concentrate and magnify light which passes through it.
A convex ray diagram helps us understand how light rays behave when passing through a convex lens. It shows us how the rays converge or diverge after passing through the lens, helping us predict where the image will form. This diagram is important for studying optics and understanding how lenses work in devices like cameras and eyeglasses.
Yes, a macro lens would be a good start as well as a few other important things to work with to make your photography hobby a success and a pleasure to work with.
A telescope uses a convex lens to gather and focus light, a concave lens to correct spherical aberration, and a flat mirror to reflect and redirect the light towards an eyepiece or sensor. These components work together to magnify distant objects and allow for detailed observations.
