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 ???
How is a magnifying mirror made?
A round piece of plate glass is heated and slumped over a curved steel form then silvered on the convex side. Better ones were made by grinding and polishing a convex surface to one side of flat window glass then silvered on the curved side.
What are some uses for the plane mirror other then to look at yourself or put on your make-uprother then to put your make-up on or look at yourself?
Plane mirrors are flat mirrors, so bathroom mirrors or even clothes shops mirrors are known as flat mirrors.
When were deformed mirrors invented?
Parabolic mirrors were described and studied in classical antiquity by the mathematician Diocles in his work On Burning Mirrors. Ptolemy conducted a number of experiments with curved polished iron mirrors, and discussed plane, convex spherical, and concave spherical mirrors in his Optics.
Why silver is used for making mirrors?
It is responsible for the reflecting action of plane mirrors.-byGitesh Khanna
What type of mirrors are on cars?
Silvered Glass mirrors. Or regular mirrors for those that don't understand Silver and/or glass
Why is silver used in making mirrors?
silver is used in making mirrors because silver has a property to reflect so it is used in making mirrors
What is winker mirror of a car?
Mirrors with Backside light (Signal Lights)
What has the author J M Freese written?
J. M Freese has written: 'Effects of outdoor exposure on the solar reflectance properties of silvered glass mirrors' -- subject(s): Reflectance, Heliostat, Mirrors
Did ancient Chinese people have mirrors?
Yes, as did many other ancient peoples including the Greeks, Romans and Egyptians. However, these were often polished smoothed metal mirrors rather than the silvered glass versions we have today.
What is an object that can reflect the most light?
A mirror would be the most effective object for light reflection. Typically mirrors are "Silvered" using either silver or aluminum on the back and the light passes through glass to the silver and bounces back. However, astronomical mirrors have the mirrored surface on the front which will reduce distortion
Why is it seven years bad luck if you break a mirror?
mirrors used to be hand silvered and brillent cut which made them extremely expensive. So if a servant broke a mirror it would take them seven years to pay for them!
Why are mirrors painted red on the backside?
Mirrors are painted red or gray on the back to make the glass reflective. If the back of the mirror was not painted a mirror would only be a sheet of glass. The paint also protects the reflective surface from being scratched on the back.
If you spray the back of glass with silve paint will that show reflection?
Not properly. There are two ways to make a mirror: Domestic mirrors are silvered (with metallic silver) on the back surface (because people touch the front) of the glass then this silver layer is coated with protective paint and plastic. A domestic mirror lasts a long time. Astronomical mirrors are silvered (with metallic aluminum) on the front surface of the glass (so the light does not have to pass through the glass to be reflected) by evaporating the aluminum metal onto the glass. An astronomical mirror needs frequent re-silvering.

· Hubble telescope The two most common elements in the universe are Hydrogen and Helium. Space is full of the stuff. -- the Half-silvered mirrors in the Hubble telescope -- Halogen atoms -- Halley's Comet -- Hertzian waves
What is a refraction of a mirror?
It splits in differents colors according to their different wave length. An example of refracted light is a rainbow. The ray is split in 7 colors: red, orange, yellow, green, blue, indigo and violet.
Is a mirror's surface transparent?
Not if the mirror is front silvered.
