An object is placed at the centre of curvature of a concave mirror. The focal length of the mirror is 20cm. A plane mirror is placed on the left of the object as shown in the figure. Considering the image formed by the plane mirror as the object for the concave mirror, where will the new image be formed?
Draw a ray diagram to show the formation of image of an object placed beyond the centre of curvature of a concave mirror. State the position, size and nature of the image.
