Draw ray diagrams for the cases of images obtained in concave mirrors as described in the table given below.
Si No | Position of the object | Position of the image |
1 | Between pole and focus | Behind the mirror |
2 | At the focus | At infinity |
3 | Between focus and centre of curvature | Beyond the centre of curvature |
4 | At the centre of curvature | At the centre of curvature |
5 | Beyond the centre of curvature | Between the centre of curvature and focus |
6 | At a very large(infinite) distance | At focus |
