Image formed by concave mirror
1. When an object lies at infinity: when an object lies at infinity, its image will be formed at principal focus which will be real, inverted, and points in size, as shown in the figure.
2. When an object lies beyond C: when an object lied beyond C, the image is formed between principal focus and center of curvature which is real, inverted, and diminished, as shown in the figure.
3. When an object lies at C: when an object lies at the center of curvature, the image formed is real, inverted and equal in size at Center of curvature.
4. When an object lies between C and F: when an object lies between C and F, the image is formed beyond C which is magnified, real and inverted.
5. When an object lies at F: when an object lies at principal focus, its image is formed at infinity which is real and highly magnified.
6. When an object lies between F and P: when an object lies between principal focus and pole of the mirror, the image formed is magnified, virtual, and erect.
