Question

1. Draw ray-diagrams to show the formation of images when the object is placed in front of a concave mirror (converging mirror):
   1. between its pole and focus
   2. between its centre of curvature and focus.
      Describe the nature, size and position of the image formed in each case.
2. State one use of concave mirror based on the formation of image as in case (i) above.

Answer 1

1. 1. When the object is placed between the pole and the focus of a concave mirror, the image formed is virtual, erect, and larger than the object.
      
   2. When the object is placed between the centre of curvature and the focus of a concave mirror, the image formed is beyond the centre of curvature. The image obtained is real, inverted, and larger than the object.
      
2. One use of a concave mirror, based on the formation of images, is that it is used as a shaving mirror.
