  Draw ray diagrams showing the image formation by a concave mirror when an object is placed (a) between pole and focus of the mirror (b) between focus and centre of curvature of the mirror (c) at centre of curvature of the mirror (d) a little beyond centre of curvature of the mirror at infinity

Answer:

                    (A) The enlarged, virtual and erect image forms behind the mirror when the object is placed between pole and focus of the mirror.     (b) The enlarged, real and inverted image forms beyond centre of curvature when the object is placed between focus and centre of curvature of the mirror. (c) The real and inverted image equal to the size of object forms at centre of curvature when the object is placed at the centre of curvature of the mirror. (d) The diminished, real and inverted image forms between centre of curvature and focus when the object is placed a little beyond centre of curvature of the mirror. (e) The real, inverted and highly reduced image forms at focus F when the object is placed at infinity.
