Large concave mirrors are used in solar furnaces Give reason?
Hassanamanullah
The shape of concave mirrors catches and directs the sun light inward which provides greater heat retention. This allows the heating system to achieve a higher temperature and be better suited to heat your entire home. A flat or convex mirror would reflect a lot of the light outward, thus making those shapes less efficient for gathering solar heat.

What are the uses of plane convex and concave mirrors?
Some convex mirrors are used for magnification... such as those you might see at a make-up counter in the store. Concave mirrors are used in stores. They're put up in the corners so that a large area can be seen that would otherwise be out of view. The also have very specified uses for bouncing lazers and those sorts of applications.
What is the difference between parabolic and concave mirrors?
In the case of concave mirrors parallel rays, parallel to the principal axis and incident near the pole(axial rays), after reflection will converge to the principal focus.Rays reflected from the marginal portions of the mirror(marginal rays) will converge to points nearer than the focus. Due to this the image formed by a concave mirror of large aperture will be blurred. This defect is called spherical aberration. This defect can be overcome by using parabolic mirrors. In a parabolic mirror all the rays, axial rays as well as the marginal rays, incidenting on it after reflection will converge to the same principal focus. This is due to the geometric property of the parabola, that is parabola allows only one focus.Hence in a parabolic mirror there is no spherical aberration and the image will be sharp and clear.
In a radio telescope radio waves strike a large curved?
Concave dish
Why the cinema screen is concave position?
The screen is curved to correct the focus at the edges. With a large screen, the distance to the edges from the centre is enough to affect the focus from the projector.
Which optical instrument uses a large concave mirror a plane mirror and a convex lens to gather light focus and enlarge an image?
You could make a Newtonian reflecting telescope with those parts.
Why concave mirror is used for shaving?
Some people use concave mirror because when a man stands between the principal focus and pole of a concave mirror,he sees an enlarged,erect and virtual image of his face.this is the reason why a concave mirror of large focal length is used for shaving. concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting. because when a man stands between the pricipal focus and pole of a concave mirror , he sees enlarged ,erect and virtual image of his face .that is why concave mirror of large focal length is used for shaving

Can concave mirrors can burn paper?
yes you can because when the light ray which comes from infinity after reflecting it converge in focas and then large number of heat occur and it burns the paper but paper should be kept in focas
You can reduce your vehicle's blind spot by?
adjusting your rear view and side mirrors properly Edit: Or Installing large side mirrors
Why are concave mirrors used in headlights of cars?
Car headlamps use parabolic mirrors to concentrate and focus the light in one direction. Without these mirrors, one would either waste the undirected light or the light would shine in all directions, which would blind the driver.
Where can large mirrors be purchased?
Shopping for large mirrors online or at local IKEA store is a great place to find good deals. Simply Mirrors offers a wide selection on mirrors in various sizes and offer excellent deals.
Compare the image formed by a concave lens and the image formed by a convex mirror?
the image formed by convex lens are real but the images formed by concave lens are virtual concave mirror are commonly used in to torches search light and vehicles headlights to get powerful parallel beam of light they are often used as a wing a to see a larger image of the face the dentist use a concave mirrors to see larger image of that is open send large can give are used to concentrate sunlight to produce heat in solar furnace

Two types of mirrors found in an astronomical telescope?
Reflecting telescopes are clearer according to scientists. These are the ones with mirrors. You could use a bunch of mirrors and reflect them to the same destination and procure an excellent picture.
What is an industrial furnace?
Industrial furnaces are used for heating large areas. They can be purchased new and used. Several hits as to where to purchase are Used Furnaces, Grieve Corp and Furnace Brokers.
When driving a large truck if you can't see the truck's two outside mirrors you are?
You don't have your mirrors adjusted correctly.
What was natural gas used for?
It is piped into a large portion of American homes for furnaces, ovens and etc.
