0When an object is placed at different positions in front of a concave mirror, various types of images are formed, which can clearly understood by considering following situations:
Object place in between pole and focus: When the object is placed in between the pole and principle focus of a concave mirror, the image is formed behind the mirror, the image formed is virtual , erect and magnified i.e., larger in size than those of the object.
Object at focus: When the object is placed at the focus of a concave mirror, the image formed is at infinity highly magnified, real and inverted.
Object between focus and center of curvature: When the object is placed between the focus and centre of curvature of a concave mirror, the image is formed beyond the centre of curvature. The image formed is real, inverted and magnified in size of the object
