Reflection from a Concave Mirror
The image is real light rays actually focus at the image location). As the object moves towards the mirror the image location moves further away from the mirror and the image size grows (but the image is still inverted).A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens. Due to the diverging rays, it is called a diverging lens.
Plane mirrors and convex mirrors will always produce an upright image. Plane mirrors and convex mirrors only produce virtual images. Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror's surface.
A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
In the U.S., passenger-side mirrors are convex (curved slightly outward), whereas driver-side mirrors are flat.
Flashlights. Concave lenses are used on flashlights to magnify the light produced by the bulb. The light falls on the concave side of the lens, and the rays diverge on the other side, thereby increasing the apparent radius of the light source and providing a wider beam.
The shape of the mirror also makes a difference in our perception. In the U.S., passenger-side mirrors are convex (curved slightly outward), whereas driver-side mirrors are flat.
Concave mirrors are used in headlights and torches. The shaving mirrors are also concave in nature since these mirrors can produce enlarged clear images. Doctors use concave mirrors as head mirrors to have a clearer view of eyes, noses, and ears. The dental mirrors used by dentists are also concave.
The side-mounted convex mirror allows greater angular visibility to the sides. In highway travel, the flat mirror lets the driver see only one lane of traffic to the sides. The convex mirror, however, reflects vehicles which are adjacent to your own vehicle, a feat which the flat mirror cannot do.
For example, the passenger-side rear view mirror on a car is convex. You may have noticed that many of these mirrors say "Objects in mirror are closer than they appear." This is because the objects are made smaller by the mirror, so they appear farther away! Makeup mirrors and dental mirrors are concave mirrors.
Convex mirrors are used for security purposes in stores because they broaden the reflected field of vision, allowing clerks to see a large section of the store. The images are smaller than the objects, but the mirrors help to see a wide area.
Concavemirrors recede in the center and bulge at the edges, like a bowl turned right-side up. This type of mirror can make an object look either larger or smaller, and either upside-down or right-side up, depending on its distance from the mirror.
