How do you solve a convex mirror?
The equation of convex mirror do = object distance, di = image distance, h = P P’ = object height, h’ = Q Q’ = image height, F = the focal point of the convex mirror. Always remember the sign rules of the convex mirror when using this equation to solve the problems of the convex mirrors.
How can you identify a mirror without touching?
Yes, we can distinguish between concave and convex mirrors without touching them. As we know that in a concave mirror the size of the image formed is enlarged w.r.t. the real image. And in the convex mirror the size of the image formed is diminished w.r.t. the real image.
What is concave mirror with example?
Concave mirror v/s convex mirror – result
| Concave mirror | Convex Mirror |
|---|---|
| The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. | The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc. |
What is V in mirror formula?
It is also known as a mirror formula. In a spherical mirror: The distance between the object and the pole of the mirror is called the object distance(u). The distance between the image and the pole of the mirror is called Image distance(v).
What if image height is negative?
When the image distance is negative, the image is behind the mirror, so the image is virtual and upright. A negative m means that the image is inverted.
Is concave real or virtual?
Concave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real—meaning that the image appears on the same side of the mirror as the object.
What is the mirror formula?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
How to determine the value of an antique mirror?
Inspect the back for a mark or tag indicating the maker and place of origin. Antique mirror frames can be made from wood, metals or a composition material such as plaster. 3. Look for Clues in the Frame
Where can I get an appraisal for an old mirror?

Is there a correlation between the age of a mirror and its value?
You’ve owned the mirror for years, yet know nothing of its past or value. In most cases, a direct correlation exists between the age of a mirror and its value. Mass-produced examples from the early 20 th century do not command the same price as handcrafted antique mirrors from the 1800s and earlier.
How can you tell if a mirror is a reproduction?
Reproduction mirrors may have the same shape or style as their true antique counterparts, or a new mirror may be housed in an old frame. Telltale signs of age, such as oxidation and scratches, help determine whether that prized mirror is a reproduction or true antique.
