A convex lens
A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
A convex lens is thicker in the centre than the outsides. A concave lens is thinner in the centre than the outsides.
The edges of a convex lens are thicker than the middle.
Dutch maker of spectacles who invented the first compound microscope in 1590 (a compound microscope is one which has more than one lens). The lens in the eyepiece was bi-convex (bulging outwards on both sides), and the lens of the far end (the objective lens) was plano-convex (flat on one side and bulging outwards on the other side). This advanced microscope had a 3 to 9 times power of magnification. In 1608 he made the first telescope together with Hans Lippershey.
In a convex lens, the middle is thicker than the outer rim. In a concave lens, the outside rim is thicker.
Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
