Only a convex lens forms any kind of real image and the size of the image is dependent upon the focal length (hence the curvature and and substance) of the lens.
A concave lens forms a virtual or imaginary image in front of the lens. It is one that cannot be projected onto a surface. Perhaps what you mean has to do with convergence and divergence. A convex lens causes light rays to converge (come together at a point), while a concave lens causes rays to diverge.

What types of images are produced by a concave mirror?
A concave mirror is dished in ward. A convex mirror domed. Both images will be distorted in size from actuality. A convex mirror will give a wider view of what you are looking at in the mirror. A concave mirror will compress and magnify the image being viewed.
Wing mirror is convex or concave?
The wing mirror or side mirror of a car is convex. It curves out to be able to see with a wider angle.
How can you identify the three types of mirrors without touching?
In the plane mirror, our image will be seen as same size of us and erect. In case of concave mirror, our image will be inverted. This is because concave mirror forms real, inverted image when object is placed behind the focus of the mirror. In case of convex mirror, the size of the image will be diminished, or smaller than us and the image will be erect too. This is because the image formed is virtual and erect.
What is true about convex mirrors?
Well first off, convex mirrors are diverging mirrors, which means when they reflect light rays, the light rays never meet. The image that forms when an object is any length away from the mirror, the image is VIRTUAL and erect, the height of the image is smaller than that of the object, and the image is always between the focal point and the vertex of the mirror. Hope that helped!
What is the use of concave and convex mirror?
Concave mirrors are used to focus light, to produce a parallel beam in car headlights, and so you can have a close look while shaving. Convex mirrors are used for making telescopes, viewfinders in vehicles, and used in supermarkets or stores as surveillance as it gives a wider view.

What is concave mirror?
A mirror in which the face dips in. As opposed to a convex mirror in which the face is rounded out for a wider view.

What is the difference between concave and convex lens'?
Answer #1convex lens is something they put in your eyes as contacts or in your glasses if you farsited but convex lens makes your image bigger and concave lens makes your image smaller.Answer #2For example, mirrors can be convex, concave and straight, just like glass. The normal mirrors that you use to look at yourself are straight mirrors, they show a normal picture.Do you ever walk into a shop and see a huge bulging mirror in the corner of the shop and you can see just about every corner of the shop in the mirror? well that is a convex mirror. The curved mirrors show a wider view of everything.The concave mirrors are opposite, they "magnify" the image, the concave mirrors make objects larger because the light is focused on a smaller reflection area.This is exactly what happens if you look through glass, that is either a convex or concave.People who are short sighted have glasses with a concavelens, (the lens that indents, you can also remember that it is concave that way because a cave goes in and a concave lens goes in.People who are long sighted wear glasses with convexlenses.
The uses of convex and concave mirrors?
Convex mirrors are used in the rear view mirror of cars because they give an erect and virtual image of the traffic behind. They let us see a wider view of the traffic. Concave mirrors are used by the dentists to see a larger image of our teeth. They are used as solar furnaces to reflect the light on the focus .They are even used in shaving mirrors. concave mirrors are used in reflector type telescopes. Concave mirrors are used by doctors to focus light into ears,throat etc. concave mirrors are used to focus light for heating purposes.
What are the uses of concave lens and convex lens?
They are used mainly for better sight. Here's an example of each. Convex is shaped like this ) which gives a wider angle. They are often used in convenience stores. Concave are used in side mirrors of vehicles They both provide different reflections. Much more effective than just a flat mirror for some purposes.

Why the street light refelector are convex in nature?
this is because convex surfaces , being curved outside, have a wider field area. Car rear view mirrors are also a good example of this. In these, convex mirrors are used. This is because, convex mirrors, being curved outside, have a wider field area and show the image of a larger area
What is concave and convex?
The best example would be to take a metal spoon that is shiny. Look at the spoon so the curved part is facing away from you. The dip you can see is called Concave. The other side that protrudes is called Convex. When you look at the concave side your face will appear squashed, wider at the top and bottom but very narrow in the middle. When you look at the convex side, your face will appear wide and fatter, almost like a football. This is because of the light rays reflective at a different angle.
How is a concave mirror shaped differently from a plane mirror?
A normal mirror is flat, like this: l . A concave mirror on the other hand, has a slight inward curve, like this: ( . And, if you're interested, a convex mirror has a slight outward curve, like this: ) . This is to provide a wider view.
