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.
A concave mirror can make objects appear bigger if they are placed between the mirror's focal point and the mirror. Objects beyond the focal point will appear smaller. Additionally, a concave mirror can reflect a wider field of view compared to a flat mirror, allowing you to see more of your surroundings.
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.
Concave lenses make things appear smaller, as they refract light. Check it out on wikepedia!

What concaave lenses and convex lenses make things look smaller?
Concave lenses make objects look smaller when they are placed close to the lens, while convex lenses make objects look smaller when they are placed far from the lens. This effect is due to the way light rays are refracted by the different lens shapes, causing the image to appear reduced in size.
Do convex mirror make things bigger or smaller and one example of where convex mirror is used?
Convex mirrors make things appear smaller as they produce virtual and diminished images. An example of where convex mirrors are used is in side-view mirrors in cars to provide a wider field of view for the driver.
How does a concave lens make things smaller?
A concave lens diverges light rays that pass through it, causing them to spread out. This spreading out of light results in the image appearing smaller when it reaches the eye. This is why objects viewed through a concave lens appear smaller than when viewed with the naked eye.
Which type of lens magnifies convex or concave?
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)
What is the difference between concave mirror and convex mirror?
A concave mirror converges light rays to a focal point, forming real or virtual images depending on the object's position relative to the mirror. On the other hand, a convex mirror diverges light rays and creates only virtual, upright, and diminished images. Concave mirrors are commonly used in reflecting telescopes, while convex mirrors are often found in car side mirrors for a wider field of view.
What mirror is used in automobiles for rear view is it concave mirror dr talwalkar talwalkardataone.in?
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.
What shape is a concave mirror and what do things look like in it?
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.

What is a polygon difference shape Concave and Convex?
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.

Does mirror make things look bigger?
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.

What kinda mirror on the back of a spoon?
A concave mirror is usually used on the back of a spoon. This type of mirror curves inward, allowing it to reflect light in a way that magnifies the image. It is commonly found in things like makeup mirrors or dentist's tools.
Are bigger thing always heavier than smaller things?
No
