yes concave is like a cave
From the point of view of the viewer, it is concave.
Your question needs more information. Convex means a surface curves out, while concave means the surface curves in.
A concave mirror bulges away from the incident light. The image of an object depends on where exactly the object is placed - relative the to focal length of the mirror. See the attached link for more details.
A concave octagon has is an 8-sdided figure in which one or more vertices (interior angles) are more than 180° , producing a shape with an inward bow, or a concavity (think of a cave).
No
From the point of view of the viewer, it is concave.
A concave mirror has a surface that curves inward like a bowl. When parallel light rays approach a curved surface and strike at different points on the curve, each ray will reflect at a slightly different direction :) Hope this answers your question
no concave mirror is in shape of concave mirror
a figure or shape that curves in not out
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
Convex. The hearts inward point makes this so.

The concave shape focuses the light into a narrow beam. If the mirror was convex, the light would be spread out - useless for searching into any distance.
Imagine if you cut a mirror shaped like a ball in half. The inside half is the concave mirror, and the outside half is a convex mirror.
The shape of a concave lens is such that the middle part is thinner than the edge. If one side of the lens is flat, then the other side will be shaped inward like a cave, kind of like this: [( You can also have a concave lens where both sides are shaped inward, like this: )( You can even have a concave lens where one side is shaped outward, and the other side is shaped inward, as long as the inward-shaped side is more dramatic than the outward-shaped side.
