Draw the ray diagram of the image formed by a concave mirror under the following conditions and also write the position and properties of the image formed.
1. Object placed beyond center of curvature.
2. Object placed at center of curvature.
3. Object placed in between center of curvature and principal focus.
4. Object placed at infinity.
5. Object placed at principal focus.
6. Object placed in between principal focus and pole of the mirror.

Answer:
1. The following diagram shows the formation of image by a concave mirror for an object beyond its center of curvature.
The image is formed between the center of curvature C and the focus F, when an object is placed beyond the center of curvature C.
The three characteristics of the image are as follows :
•The images are real
•The images are diminished
•The images are inverted
2.Image of an object placed at center of curvature is inverted, real and of the same size and is formed at the center of curvature. Hence image will be real and at the center of curvature (20 cm from mirror).
3. When the object is placed between centre of curvature and principal focus of a concave mirror the image formed is beyond C as shown in the figure and it is real, inverted and magnified.
4. When an object is at infinity,then the rays coming from it is almost parallel to principal axis. Hence the image formed is at focus.
5. When the object is placed between principal focus and pole of a concave mirror, an enlarged, virtual and erect image is formed behind the mirror.
6. When the object is placed between principal focus and pole of a concave mirror, an enlarged, virtual and erect image is formed behind the mirror.

Answer:
HyperText Markup Language (HTML) is a simple markup system used to create hypertext documents that are portable from one platform to another. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of applications. HTML markup can represent hypertext news, mail, documentation, and hypermedia; menus of options; database query results; simple structured documents with in-lined graphics; and hypertext views of existing bodies of information.
