To construct a ray diagram, we use two light rays which are so chosen that it is easy to know their directions after reflection from the mirror. List these two rays and state the path of these rays after reflection. Use these rays to locate the image of an object placed between centre of curvature and focus of a concave mirror.(All India - 2012)

- focus focus full length is the answer of the two characte to draw ray doagram
Reflection and ray diagram of concave mirror
Explanation:
Reflection
It is the bouncing of light rays on striking the surface .
Characteristics of Best reflector
It should have shiny, polished and smooth surface .
Mirrors
The types of mirror :
- Concave mirror
- Convex mirror
Concave mirror
In it there are certain rules to be followed to obtain image :
1st case : The ray coming parallel to principal axis , after reflection passing through focus .
2nd case : The ray coming from Center of curvature , passes straight .
3rd case : The ray passing through focus after reflection becomes parallel to principal axis .
Lets see the image formed when object is placed between Center of curvature and focus of concave mirror .
Image is formed beyond C , Image is real , inverted and magnified .
The ray diagram is given .
