The mold for a concave object is convex.The mold for a convex object is concave.
1/a+1/b=1/f
Magnifying glasses use convex lenses
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).

You would use a convex lens.

Here is a description of image formation in a concave mirror: if the object is beyond the center of curvature (F), the image formed is real and upside down; if the object is very near to the concave mirror, the image forms behind the mirror. It is virtual, upright, and bigger in size. Here is a description of image formation in a convex mirror: a convex mirror always produces a virtual, upright, and smaller image of the object at any distance in front of it. The image is located behind the mirror.
Concave and convex lenses both enlarge an object to a certain extend.
convex converging apex... :P
THough all are erect, in concave it will be enlarged in plane mirror of the same size as the object but in convex mirror it will be dimished
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
A concave surface is hollow and bends inwards.... think of it as conCAVE.... caves are hollow.A convex surface is like a bump and bends outwards... a convEX bump is on the EXterior of an object
