What are the uses of convex and concave mirrors?
A convex mirror decreases the size of the image and increases the field of view. A concave mirror is capable of producing virtual and enlarged images of objects when kept between the focus and pole of the mirror . This property is used in the making of shaving mirrors to get a large and clear view of the face.
What are the 5 uses of convex mirror?
Two uses of convex mirror are: (i) It is used as a rear view mirror in vehicles. (ii) It is used as a vigilance mirror. (iii) it is used as a reflector in street lamps .
How are convex mirrors used at school?
Convex mirrors are used in school class and libraries to see the full view of the area . This is possible because images formed by convex mirror is smaller in size and therefore offers a wide field of view.
How convex mirrors are used?
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 some examples of convex mirrors?
The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc .
Which mirror is used in street light?
A plane mirror is used in a microscope, mirror tiles, for signaling and periscopes. Hence, comparing all the given options, it can be concluded option B is correct; a street light bulb uses the convex mirror as reflectors.
What is the two uses of concave mirror?
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.
Where is convex lens used?
Convex lenses are used in eyeglasses for correcting farsightedness , where the distance between the eye’s lens and retina is too short, as a result of which the focal point lies behind the retina. Eyeglasses with convex lenses increase refraction, and accordingly reduce the focal length.
Where do we use concave mirrors in our daily life?
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.
How mirrors are used in our daily life?
Mirrors serve many functions for us: letting us see ourselves when we put on makeup , wash our faces, try on clothes and more. This is also true for much of the animal kingdom; as peacocks, apes and elephants like to admire their own reflection too. When I brush my teeth, I can see exactly where I need to reach.

- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
What are the four uses of convex mirror?
- Inside buildings.
- Vehicle mirrors.
- Magnifying glass.
- Security purposes.
What does convex look like?
A convex shape is the opposite of a concave shape. It curves outward, and its middle is thicker than its edges . If you take a football or a rugby ball and place it as if you’re about to kick it, you’ll see that it has a convex shape—its ends are pointy, and it has a thick middle.
What is difference between convex and concave mirrors?
A convex mirror is curved outwards, and concave mirror is curved inwards. (B). The focal point is in front of the convex mirror, and for a concave mirror, it is behind. ... The fundamental difference between them is that the reflective surface of a concave mirror is inside the sphere and that of a convex mirror is outside .
How do convex mirrors form images?
How do convex mirrors work? A convex mirror is a diverging mirror in which the reflective surface bulges towards the light source. They are not used to focus light as they reflect light outwards. The image formed by convex mirrors are smaller than the object but gets larger as they approach the mirror .
