For a concave mirror, if an object is lying at infinity then image will be formed at:
beyond the mirror
focus
beyond center of curvature
in between f and C
Question 30 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 (e) at infinity
The image formed by a concave mirror is real, inverted and highly diminished (much smaller than the object). The object must be : (a) between pole and focus (b) at focus (c) at the centre of curvature (d) at infinity
