Draw a ray diagram to show the image formation by a concave mirror when the object is kept between its focus and the centre of curvature. Using this diagram, derive the mirror formula.
Show Hint
For a concave mirror:
\[
\frac{1}{f}
=
\frac{1}{u}
+
\frac{1}{v}
\]
Magnification:
\[
m=-\frac{v}{u}
\]
Object between \(F\) and \(C\):
• Image beyond \(C\)
• Real
• Inverted
• Enlarged
