The main difference between a convex and concave mirror lies in the image formed by the two mirrors, i.e. while convex
mirror forms diminished image
, the concave mirror either forms an enlarged image or a diminished one, depending upon the position of the object.
What is the difference between concave and convex lens?
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.
What is the difference between a concave mirror and concave lens?
A concave mirror is opaque whereas a
concave lens is transparent
. A concave mirror can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object whereas a concave lens forms only virtual, diminished and erect images for all positions of the object.

What are the 3 main differences between a convex and concave mirror?
| Concave mirror Convex mirror | It is also called a converging mirror. It is also called a diverging mirror. | It has a real focus. It has a virtual focus. | The magnification of a concave mirror can be greater, equal or less than 1. The magnification of a convex mirror is always less than 1. |

What are the examples of concave lens?
- Binoculars and telescopes.
- Eye Glasses to correct nearsightedness.
- Cameras.
- Flashlights.
- Lasers (CD, DVD players for example).
Where is convex lens used?
Convex lenses are used in
microscopes, magnifying glasses and eyeglasses
. They are also used in the cameras to create real images of objects present at a distance.
What is concave mirror with example?
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.
What are the applications of concave mirror?
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
What is called concave mirror?
A concave mirror, or
converging mirror
, has a reflecting surface that is recessed inward (away from the incident light). … These mirrors are called “converging mirrors” because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus.
How are convex mirrors used in everyday life?
Convex mirrors are
used inside the buildings
, They are also used in making lenses of sunglasses, They are used in the magnifying glass, They are used in securities and they are used in telescopes.
What are the 3 types of mirrors?
- Plane Mirror — These are flat mirrors that reflect images in their normal proportions, reversed from left to right. …
- Concave Mirror — Concave mirrors are spherical mirrors that curve inward like a spoon. …
- Convex Mirror — Convex mirrors are also spherical mirrors.
What are the similarities between concave and convex mirrors?
Both converge parallel rays to a focal point,
have positive focal lengths, and form images with similar characteristics
. A concave lens acts a lot like a convex mirror. Both diverge parallel rays away from a focal point, have negative focal lengths, and form only virtual, smaller images.
What is concave mirror Class 8?
A concave mirror has
a reflective surface that is curved inward and away from the light source
. Concave mirrors reflect light inward to one focal point. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.
What are the examples of convex mirror?
| Concave mirror Convex Mirror | The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc. |

What is the focal length of concave mirror?
Focal Length –
The distance between the pole P of the concave mirror and the focus F
is the focal length of the concave mirror. Thus, the focal length of a concave mirror can be estimated by obtaining a ‘Real image’ of a distant object at its focus, as shown in the figure.
