||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.

Is a Spoon concave or convex?
The inner surface of a spoon acts like a concave mirror, while its outer surface acts like a convex mirror. We know that the image of an object formed by a plane mirror cannot be obtained on a screen.
What shape is concave?
Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).
Which side of spoon is convex?
The curved surfaces of a spoon act like mirrors. The front part of the spoon is concave while the back side of the spoon is convex.
Why do we see inverted image in a spoon?
The rays coming from the upper part of the object are reflected downwards, while the rays from the lower part of the object are reflected upwards. This results in the formation of an inverted image. This is the reason we see inverted images in a spoon.
Is a mirror a convex?
Both the center of curvature and the focal point are located on the side of the mirror
opposite the object. As the focal point is located behind the convex mirror
, a mirror
is said to have a negative focal length value.

Is concave lens?
A concave lens is a type of lens that diverges a straight light beam coming from the source to a diminished, upright, virtual image is known as a concave lens. It can form both real and virtual images. Concave lenses have at least one surface curved inside.
Who uses concave lens?
A concave lens is used to diverge incident rays. This helps to create a virtual image on the opposite side of the refracting surface. Hence, these lenses are used in binoculars, telescopes, cameras, flashlights and eyeglasses.
What are the examples of concave lens?
are binoculars, telescopes, eyeglasses, cameras, flashlights and lasers.
- Binoculars and telescopes.
- Eye Glasses to correct nearsightedness.
- Lasers (CD, DVD players for example).
Where is concave mirror used?
Concave mirrors are widely used in headlights of automobiles and motor vehicles, torchlights, railway engines, etc. as reflectors. The light source is placed at the focus of the mirror, so after reflecting the light rays travel over a huge distance as parallel light beams of high intensity.
What are the two uses of concave mirror?
Light Energy | Short/Long Answer Questions
Solution: Two uses of concave mirror are: (i) They are used as a reflector in the headlights of cars and in search of light. (ii) Doctors examine the throat, ear, nose and eyes with light focus with the help of a concave mirror.
What is concave mirror and its uses?
Concave mirrors are used in reflecting telescopes. They are also used to provide a magnified image of the face for applying make-up or shaving. Concave mirrors are used to form optical cavities, which are important in laser construction. Some dental mirrors use a concave surface to provide a magnified image.
What is the use of convex and concave mirror?
Question 8. Q8) Give one use each of a concave and a convex mirror. Concave mirror is used by dentist, solar furnace, reflector of a torch, etc. Convex mirror is used in rear view mirrors.
What are three uses for Convex mirrors?

What is convex and concave mirror?
What are convex and concave mirrors? If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Image. Concave mirrors can form inverted and real images and also virtual and erect images.
What are the 5 uses of convex mirror?
- Inside buildings. You might have noticed that large office buildings, stores, hospitals, and other many other buildings have convex mirrors in the corners.
- Sunglasses. We might have used sunglasses many times.
- Vehicle mirrors.
- Magnifying glasses.
- For security purposes.
- Street light reflectors.
Why do we use convex mirrors?
These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards. The convex mirror is also used to provide safety for motorists on roads, driveways and in alleys where there is a lack of visibility.
What are the applications of convex lens?
Uses Of Convex Lens
- Magnifying glasses.
How are convex mirrors used in everyday life?
