Characteristics of concave and convex mirror
What are the characteristics of concave mirror?
Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.
What are the characteristics of convex mirror?
Properties of Convex Mirror
A convex or diverging mirror is also known as a diverging mirror as this mirror diverges light when they strike its reflecting surface. Virtual, erect, and diminished images are always formed or observed with convex mirrors, irrespective of the distance between the object and the mirror.
What are the four characteristics of convex mirror?
Solution : Properties of image formed by a convex mirror : <br> (1) It is always formed behind the mirror between the pole and its focus. <br> (2) It is always virtual and erect. <br> (3) Its size is always smaller than the object. <br> (4) Magnification is always positive.
What are the 3 main differences between a convex and concave mirror?
Basically, the reflecting surface of the convex mirror bulges outside while the concave mirror bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while enlarged images form in concave mirrors.
What are the characteristics of concave mirror Class 7?
Properties of a Concave Mirror
Firstly, for a spherical mirror-like CM the focal distance is half of the radius of the focal length. Secondly, the mirror reflects the ray of light from the centre on the same path. Lastly, the image form by CM can be real or virtual.
What is the difference between concave and convex mirror?
A concave mirror is a spherical mirror with an inwardly curved reflection surface, whereas a convex mirror is a spherical mirror with an outwardly bulged reflecting surface.
What is the difference of convex and concave?
Convex. Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).
What is convex and concave mirror Class 7?
Concave mirror
Convex mirror. Spherical mirrors whose inner side is reflecting are called concave mirrors. Spherical mirrors whose outer side is reflecting are called convex mirrors. It’s focus and centre of curvature lies in front of the motor.
What are the five uses of concave mirror?
Some concave mirror uses are listed in the points below.
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
What are the characteristics of convex lens?
Difference Between Convex And Concave Lens
| CONVEX | CONCAVE |
|---|---|
| This lens converges a straight beam of light. | This lens diverges a straight beam of light. |
| This lens is thicker at the centre and gets thinner as we move towards the edges. | This lens is thinner at the centre and gets thicker as we move towards the edges. |

What are the characteristics of a mirror?
- Image formed by a plane mirror is always virtual and erect.
- The size of the image is equal to that of the object.
- The image formed is as far behind the mirror as the object is in front of it.
- The image is laterally inverted.

Where is convex mirror used?
A convex mirror is used in large workplaces, stores, and hospitals to allow people to look around the corner and avoid colliding with one another. Because they can diverge light beams and create virtual pictures, convex mirrors are commonly employed as rear-view mirrors in automobiles and transportation.
What are the advantages of concave mirror?
Concave mirrors are useful for focusing. As a result, the center of the mirror is fitted with this sort of mirror, which serves to reflect light rays and cause them to travel a great distance.
What is the importance of concave and convex mirror?
Because they spread light across a larger region, convex mirrors are used as streetlight reflectors. Concave mirrors are used for a variety of purposes, including providing a powerful parallel beam of light; a concave mirror is used as a reflector in torches, searchlights, and car headlights, and among other things.
Where is concave mirror used?
Concave mirrors reflect light inward to one focal length. Hence, concave mirrors are mostly used to focus light. It collects the light and refocuses the incoming rays at the focus point. Concave mirrors are used in vehicles’ headlights, shaving mirrors, solar furnaces, searchlights, torches, makeup mirrors, etc.
Where is concave and convex mirror used?
Concave mirror is used by dentist, solar furnace, reflector of a torch, etc. Convex mirror is used in rear view mirrors.
What’s the difference between concave and convex?
Concave means “hollowed out or rounded inward” and is easily remembered because these surfaces “cave” in. The opposite is convex meaning “curved or rounded outward.” Both words have been around for centuries but are often mixed up. Advice in mirror may be closer than it appears.
