If you stand between the focal point and the pole of the mirror, then the nature of the image formed is virtual, erect and magnified. These kinds of
mirrors are a little thicker, and they bend light towards you
. … This is the reason why concave mirrors are used as shaving and makeup mirrors.
Why concave mirror is used as?
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.
Why concave mirror is not used as a shaving mirror?
Name the type of mirror used as a shaving mirror (1) Concave mirror (2) convex mirror (3) Plane mirror (4) None of above. A concave mirror is used in the case of shaving mirror
because when the concave mirror is placed very close to the object, a magnified and virtual image is obtained
.
Which mirror is used in street lamp?
Hence, comparing all the given options, it can be concluded option B is correct; a street light bulb uses the
convex mirror
as reflectors. Note: Reflectors light bulbs are generally used in the heavy light application, in floodlights and in spotlights. Reflectors are used because they can spread light in a large area.
What are the 4 uses of concave mirror?
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
Which mirror is used in telescope?
The Reflecting Telescope or Reflector uses
a concave mirror
as the telescope’s Primary Objective, rather than a lens or lenses. The type of reflector depends on other system mirror(s), called the Secondary Mirror.
Which mirror is used in Periscope?
Only plane mirrors
are used for a simple periscope. An expanded view of the object is required for some distance visions, and therefore convex mirrors are helpful. An erect image is produced by a double reversal of the object. Convex mirrors can be used to view objects that are too close to each other.
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.
Is concave mirror used in street lights?
Convex mirror are used as reflector in street lamps whereas concave mirror
is used as a reflector in torch and car headlight
.
Which mirror is used in street lights and why?
Convex mirrors
are used as streetlight reflectors as they spread light over the greater area. Concave mirrors are used for various purpose:-1) A concave mirror is used as a reflector in torches, search lights, head lights of motor vehicles etc. to get powerful parallel beam of light.
Why convex lens is used in street lights?
Convex mirrors are used as reflectors in street lights
because they are able to spread the light over a wide area
. Convex mirrors are used as reflectors in street lights because they are able to spread the light over a wide area.
What is the 5 uses of concave mirror?
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.
How do doctors use concave mirrors?
If the object is placed between the focus and pole of a concave mirror, it provides a virtual enlarged and erect image. So, the doctors use it
as a magnifying tool
.
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.
Do telescopes use mirrors?
Reflecting telescopes are sometimes called Newtonian telescopes after their inventor Isaac Newton who built the first one in 1668. They
use mirrors to collect and focus the light towards the eyepiece
. Mirrors are lighter than lenses and they are also easier to shape into a smooth and perfect surface.
Do refracting telescopes have mirrors?
A refractor uses lenses within a tube to refract (bend) light. It’s the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand,
use mirrors instead of lenses
to reflect light. Most modern observatories use reflectors because their telescopes are so huge.
