Describe the images formed in a concave mirror and in a convex mirror?

Here is a description of image formation in a concave mirror: if the object is beyond the center of curvature (F), the image formed is real and upside down; if the object is very near to the concave mirror, the image forms behind the mirror. It is virtual, upright, and bigger in size. Here is a description of image formation in a convex mirror: a convex mirror always produces a virtual, upright, and smaller image of the object at any distance in front of it. The image is located behind the mirror.


What is the difference of a concave mirror to a convex?

Concave mirror* its reflecting surface is curved inwards*it can form both real and virtual images*the centre of curvature and the focus lies in front of the mirror*it can form both enlarged and diminished imagesConvex mirror* its reflecting surface is curved outwards*it can form only virtual images*the centre of curvature and the focus lies behind the mirror*it can form only diminished images


Where should the object be placed in order to produce a larger object behind a concave mirror?

The object should be necessarily be placed between the focal point of the concave mirror and the pole of the mirror to produce a larger image(not larger object) behind the concave mirror.


What is the difference between a concave and convex lens?

Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.


Does the concave mirror in a flashlight produce light rays that converge?

Answer #1:No, the concave mirror in a flashlight produces light rays that do notconvergebecause concave mirrors reflect light waves to form images, but concave mirrorshave a surface that is curved inward.==============================Answer #2:The ideas behind the concave reflector in a cheap flashlight, the concave reflectorin an auto headlight, and the giant concave reflector of a satellite uplink, are allthe same ... to beam the energy from the focus out in a parallel 'cylindrical' beamthat doesn't converge or, as far as possible, doesn't diverge either.

Will an object inside a principal focus be smaller?

No, for a concave mirror the object will become larger. it is virtual the right way up and it is behind the mirror

Does concave lens produce a real image?

Because when you extend the light rays, they diverge and never meet. so you must always extend the light rays back behind the object, this will always result in the image being upright and erect. Meaning it will always be virtual, never real.

Is it plain mirror or concave mirror producing magnified real image?

A plane (flat) mirror reflects an image which is the same size and shape, and colour as the object in front of the mirror. A concave mirror can produce a magnified image. If the image is in front of the mirror it is a real image; if behind it is a virtual (non-real) image. A real image can be cast upon a white the best) surface

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.
