## How is a concave mirror made?

It turns out that if you rub two bars of metal (or pieces of glass) across each other with grinding paste in between, one surface naturally ends up convex, and the other concave.

### How are spherical mirrors made?

A spherical mirror is formed by cutting out a piece of a sphere and silvering either the inside or outside surface. A concave mirror has silvering on the interior surface (think “cave”), and a convex mirror has silvering on the exterior surface.

#### How are concave images formed?

Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.

Why shaving mirrors are concave?

Concave mirrors are used as shaving mirrors because when the face is placed close to a concave mirror (within the focus of the mirror) it produces a magnified and erect image of the face. Since an enlarged or magnified image of the face can be seen in the concave mirror, it becomes easier to make a smooth shave.

How are concave and convex mirrors constructed?

Explanation: Convex Mirror : Made by grinding a thick plane mirror into a bulging shape , using appropriate tools. Concave Mirror : made up of Acryl Plastic and is grounded into shape with the help of machines.

## How are concave and convex mirror made?

Concave Mirror: When the outer surface of the spherical mirror is painted, concave mirrors are formed. Convex Mirror: When the inner surface of the spherical mirror is painted, convex mirrors are formed.

### How are concave and convex mirrors formed?

When you keep an object in front of a concave mirror, an enlarged image of the object is formed when it is kept close to the mirror and an inverted image of the object is formed when it is kept at a distance. A convex mirror always forms a small and an erected image of the object.

#### Is a Spoon a concave mirror?

A mirror that curves inward is called a concave mirror, whereas one that curves outward is called a convex mirror. Pick up a well-polished metal spoon and you can see an example of each type of curvature. The side of the spoon that holds the food is a concave mirror; the back of the spoon is a convex mirror.

What type of image are formed by concave mirror?

Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object. 2.

How does concave mirror work?

A concave mirror has a reflective surface that is curved inward and away from the light source. Concave mirrors reflect light inward to one focal point. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.

## How do concave mirrors work?

### How are images formed in concave mirrors?

Image Formation By Concave Mirrors: A spherical mirror whose inner surface is reflecting is known as a Concave Mirror. A concave mirror produces both real and virtual images. Based on the distance between the concave mirror and the object, the concave mirror displays real or virtual images.

#### What is the principal axis of a concave mirror?

For a concave mirror, it lies in front of the mirror. The radius of curvature: it is the radius of the sphere formed by the reflecting part of the sphere. It is represented by R. Principal axis: it is the straight line passing through the pole and centre of curvature of the spherical mirror. This is normal to the mirror at its pole.

What are the two rules of reflection for concave mirrors?

To draw these diagrams, we will have to recall the two rules of reflection for concave mirrors: 1 Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point… 2 Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis… More

Is the concave mirror in Figure 2 flat?

The ruler seen reflected by the concave mirror to the right in Figure 2 makes it appear as if the mirror actually could be flat. It nearly is.
