Concave means that it bows inward (a dent instead of a bulge). Planoconcave means that one side is flat and the other side is concave.
concave is inward, convex is outward concave is inward, convex is outward
A concave surface curves inward. Cave-in
Convex lens converges the light and a concave lens diverges the light..
the focal point of a concave mirror is positive while a convex is negative
A concave mirror is usually used to project something onto a screen. A concave lens is usually used to view an image through the naked eye.
plano concave
concave is inward, convex is outward concave is inward, convex is outward
No - by definition. You can have a plano-convex (or -concave) lens (one side flat). Actually a purely plano "lens" would be merely a glass disc.

We get a plano-concave liquid lens held in between the two. Using this technique we find the refractive index of the liquid by getting newton's rings.
Not much except concave mirror reflects and concentrate the light and lens let trough and distorts the light "concave -the inner surface of a sphere." defines the shape of the lens or mirror
Concave curves in (like a cave) = ) and convex curves out = (
The difference between the two is that once the light passes through the concave lens it diverges, and the rays are refracted outward, and never meet a focal point. Then there is the parallel light rays that bounce off the curved surface of a concave mirror and then meet a single point ( focal point).
Right now, its 11:46 in London and 5:46 in Plano.
