You can't directly compare the two classes of lenses like that.
What you can say is:
-- The middle of a convex lens is thicker than the edge.
-- The middle of a concave lens is thinner than the edge.
One way to remember it: The middle of a concave lens is caved in.
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.
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.
A spoon that you have put some food into is a concave shape. It is a cavity. A concave lens is such that it is thicker at the edges than in the middle. Convex is the bottom of the spoon. A convex lens is thicker in the centre than around the edges.
The top of the convex lens is thicker than the bottom.
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 ---> ()
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.
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.
Convex lens are thicker in the middle. Concave lens are thinner in the middle.
Concave. The opposite- thick in middle, thin at edges- is convex.
