Is a concave or convex mirror used for passenger side mirrors?
Convex mirrors are often used for side mirrors (if the mirror has a note saying "objects in mirror are closer than they appear," it's convex; it may be convex even without such a note).
How are convex mirrors in shopping centres used for security purpose?
Similar to convex mirrors used in some parking areas, these mirrors are useful because they can be placed on the ceiling and near corners while expanding the field of view due to their convex shape. Because of this, they are often used for seeing behind people while being in front of them (with the mirror perched high on the wall behind a line of people), looking around corners, and behind yourself. Convex mirrors basically expand your view like mirrors in a car and can be useful for spotting potential thieves without even having to look directly at them. The use of these mirrors is somewhat limited because they often have blind spots and the person being spotted on the mirrors can look back into it to see if anyone is observing them.
Why do you use a convex mirror as a rear view mirror in vehicles?
"Convex mirrors are used to provide a wider Field_of_viewthan a flat mirror, and are often used on vehicles, especially large trucks, to minimise Blind_spot_(automobile)."http://en.wikipedia.org/wiki/Mirror
What happens to parallel light rays hitting a convex mirror?
Due to the positive curvature of a convex mirror, when parallel light rays hit the mirror, they are reflected outward (they diverge). As such, convex mirrors are often used for security in convenient stores and other places...because they allow for a wide area to be reflected in the mirror, allowing you to see a wide area when you look at the mirror.
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

What is a convex mirror and what is it used for?
Convex mirrors are also curved mirrors, but the silvered surface bulges outward instead of inward, as with the concave spherical mirror. As with all mirrors, the angle of incidence of a ray of light is equal to the angle of reflection with respect to a normal on the surface. On a curved surface the normal changes with the curvature. Therefore, the light rays will diverge from the object. If the rays of light are extrapolated back to the point where they converge, this will be the point where the image is formed. For reflections off a convex mirror, the image is virtual and upright. Use of Convex Mirrors: Convex mirrors are often used in car wing-mirrors because they have a greater field of view than a similar plane mirror. However the greater field of view is at the expense of making objects seem further away than they are in reality. Hence the expression seen etched on to the mirrors, 'Objects in Mirror are Closer than they Appear'. Concave mirrors are also used as security mirrors as they enable the viewer to see over a greater region of space another use for this mirror is used in making sunglasses and telescopes. bet you didn't know that did u ???

The uses of convex and concave mirrors?
Convex mirrors are used in the rear view mirror of cars because they give an erect and virtual image of the traffic behind. They let us see a wider view of the traffic. Concave mirrors are used by the dentists to see a larger image of our teeth. They are used as solar furnaces to reflect the light on the focus .They are even used in shaving mirrors. concave mirrors are used in reflector type telescopes. Concave mirrors are used by doctors to focus light into ears,throat etc. concave mirrors are used to focus light for heating purposes.
What are the two types of curved mirror called?
they are called concave mirror ... mirrors whose center bulges out are called convex, and can reflect a wider view than a flat mirrored surface, but the objects are "larger than they appear", and also "closer than they appear." These are most often seen on right hand mirrors on vehicles, to help minimise blind spots. mirrors whose center is recessed are called concave (remember the term by thinking of a shallow cave.) Depending upon how close you are to the mirror's focal point, objects appear larger than they really are, or upside down. These are often seen in makeup mirrors so you get a clearer view of your face when shaving or applying makeup. Combinations of both convex and concave mirrors are seen in funhouses of amusement parks, to make the viewer look skinnier and taller, shorter and fatter, or even upside down.

Why do you often see the object are closer than they appear written on convex mirrors?
The mirror is slightly convexed to help eliminate the "blind" spot on the passenger's side. There is a plane mirror on the driver's side and a convex mirror on the passenger's side. The reason only the passenger mirror is convex is because you are farther away from it. The angular view provided by farther mirror of the same physical size produces a similarly smaller reflected field of view. The convex mirror provides a larger field of view- one that should be comparable to the closer drivers mirror.
What are the uses of concave lens and convex lens?
They are used mainly for better sight. Here's an example of each. Convex is shaped like this ) which gives a wider angle. They are often used in convenience stores. Concave are used in side mirrors of vehicles They both provide different reflections. Much more effective than just a flat mirror for some purposes.
List of different uses of mirrors?
here are some: Car rear-view mirrors and side mirrors. Over-the-sink in the bathroom mirrors (for shaving and other uses) Full-length dressing mirrors, often found inside closets Dental mirrors Fun-house mirrors with wavy surfaces Mirrored balls hanging from the ceiling in discos Periscopes Auto mechanics use mirrors held on rods so they can examine hard-to-reach places. Torches have curved mirrors for directing the beam of light Searchlights, floodlights, and spotlights (used in theatres) have similar mirrors. In barbershops so that the customer may see the result, front and back to collect sunlight for solar power generation
What do the seeds of cosmos look like?
Cosmos seeds are small, dark brown to black in color, and slightly curved in shape. They are often described as resembling small commas or ticks.
Is a diamond a rhobus?
A diamond, like the one seen in playing cards is often a rhombus although in some cases the sides are slightly curved (inwards). A diamond, as in a lump of carbon, is not a rhombus.
