1.	Draw the ray diagram and also state the position, the relative size and the nature of image formed by a concave mirror when the object is placed at the centre of curvature of the mirror.
Answer» SOLUTION :Let an object AB be placed NORMALLY to the principal axis of a concave mirror at its centre of curvature C. When we draw a ray diagram to locate the image FORMED, we find that the image A.B, is formed at the centre of curvature C itself. The image is real, inverted image. Size of the image is exactly EQUAL to the size of the object. It means that magnification of the image is -1.
