Their behaviors are so similar and their differences so vanishingly negligible
that to any casual observer, they appear virtually identical. Controlled tests
in the laboratory environment support this widespread impression.
A thick convex lens has a larger thickness and can bend light rays more than a thin convex lens. This results in a shorter focal length and stronger focusing ability for a thick convex lens compared to a thin convex lens.
The difference is that when virtual image is formed by the concave mirror...it is larger than its original size..but when it is formed by the convex mirror..it is smaller than the original size....
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
The image of the tree formed by the convex lens is virtual, upright, and magnified.
To distinguish between a convex and concave lens using a printed piece of paper, hold the lens against the paper with the curved side facing up. If the text appears larger and clearer through the lens, it is a convex lens. If the text appears smaller and upside down through the lens, it is a concave lens.
A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()

Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.

projector have concave or convex
The lenses have different responsibilities. A optic lens is often concave which means it fold inward. An anatomy lens is mostly convex which means it folds outwards. Both lens' help you see.

they are both lenses and form images
The image of the tree formed by the convex lens is virtual, upright, and magnified.

If the text appears larger and clearer through the lens, it is a convex lens. If the text appears smaller and upside down through the lens, it is a concave lens.
The focal distance of a convex lens is always positive. It is the distance between the lens and the focal point when light rays are parallel and converge after passing through the lens.
A double convex lens is thicker in the middle and thinner at the edges, causing light rays passing through it to converge. A double concave lens is thinner in the middle and thicker at the edges, causing light rays passing through it to diverge.
