Because of it's shape a concave lens bends or refracts light outward away from the center of the lens and towards its thicker edges. The light rays never cross or meet a focal point so the image never inverts. A concave lens makes objects appear smaller than they really are.
Convex mirrors (curving outwards from side to side) make you look wider; if the mirror curves from top and bottom as well as from side to side you'll look shorter and wider.
concave mirrors (curving inwards from side to side) make you look thinner; if the mirror curves inwards from top and bottom as well you'll look shorter and thinner.
Convex lenses make things look closer and bigger; they're for far-sighted people. Concave lenses make objects seem farther and smaller; they are for near-sighted people.
Yes. B'coz its magnification is always negative.
Concave lenses make things appear smaller, as they refract light. Check it out on wikepedia!
It can be either. There's no general rule.
A concave mirror makes things look bigger
becuas no
Concave mirrors bend inward and the image will appear upside down.
Convex mirrors bend outward and the image created will be upright like the original but the reflection would be smaller.
Convex lens makes things look bigger and concave lens makes things look smaller!
Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia). Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia). A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look bigger. A concave mirror can magnify. Convex mirrors always shrinks things. They are used sometimes in offside rear vision mirrors for vehicles. A concave mirror will also shrink things if you look at the mirror from far enough away and the object you look at is also far away (but you wouldn't want to use it for a rear vision mirror because it then also turns stuff upside down). Concave lenses disperse light rays outward, rendering it impossible for them to focus incoming light onto a plane surface. Their "focus" is virtual, behind the lens on the side of the light source. If the concave surface is used as a reflector, it will form a real image. This is the basis for reflector telescopes. Further info: http://en.wikipedia.org/wiki/Lens_(optics)

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).
Other things being equal - same material, mainly - a bigger battery will store more energy than a smaller battery. If the same amount of power is used, the bigger battery will last longer. Whether this is better or not depends on the specific needs - the bigger battery will also be heavier, and use up more space.

Rear View MirrorThe kind of mirror used in the rear-view mirror must be convex mirrors, because it creates smaller, yet still upright images. Concave mirrors would create an inverted image and the cars you see are not upside down. Convex mirrors make everything smaller so this allows the driver to see a greater range of things behind him.
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.
No
Okay, you know those big mirror like things that they have in hospitals on stores to see whats coming around the corner? Well those mirror things are convex. The mirror ones that 'cave in' are concave. And they are different from a polygon because they really don't have sides like squares or rectangles:) Hope this helped.

It depends on the mirror geometry. There are three geometries for mirrors:Concave Mirror: Glass is curved inward, creating enlarged or bigger sized reflections. Useful as a grooming aide.Convex Mirror: The glass curves outward, creating reduced or smaller sized reflections. It can be either decorative or a useful tool in parking garages or busy corridors to help people see around the corner.Flat mirror: The glass is flat, creating same or equal sized reflections.
No
They can if they are curved inward (concave). We frequently see this in make-up mirrors that have a flat, or "regular" side, and a concave side that magnifies the image one sees in it.
Microscopes, telescopes, a magnifying glass, reading glasses, a concave mirror, a drop of water, a glass tube looked at from the side.
it is a square that you press and it makes things bigger and smaller as you move the mouse.
