Concave mirrors are used as
searchlights, shaving mirrors, satellite dishes
, and many more. These mirrors have the property to collimate and concentrate light rays. Concave mirrors in torches and headlights are used as reflectors.
What are concave mirrors used for?
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.
What is an example of a concave mirror?
Torch lights, automobile headlights
are examples of concave mirrors. Magnifying glasses, telescopes are examples of convex mirrors.
Where are concave and convex mirrors used?
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. A convex mirror has the property of diverging a beam of ray falling on it.
What are the 5 uses of convex mirror?

.
What are three uses of concave mirror?
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
Which mirror is used in street light?
Convex mirror
is used in street light because it has the property of divergence . Therefore light rays coming from bulb diverges in convex mirror and cover a large distance .
What are 2 examples of a concave lens?
- Binoculars and telescopes.
- Eye Glasses to correct nearsightedness.
- Cameras.
- Flashlights.
- Lasers (CD, DVD players for example).
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
.
Why are torches used in concave mirrors?
A concave mirror is used in torch lights , because
the light ray from the source placed on the focus of a concave mirror are reflected in such a way that the reflected ray are strong, straight,and parallel
.
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 does convex look like?
Definition of Convex
A convex shape is the opposite of a concave shape. It

Which mirror is used in telescope?
The major component of a reflecting telescope is the
concave mirror
. The concave mirror is known as a converging mirror because it converges a ray of light travelling from infinity, to its focal point.
Which mirror is used in solar cooker?
Note:
A plane mirror
can be used in a solar cooker but it cannot concentrate the rays at point as the concave mirror does. Thus, the maximum heat will not be achieved. A convex cannot be at all since it will diverge away the sun rays falling on it.
