If the object distance for a concave mirror is 24 cm and image distance is 12 cm in front of a mirror. Then, find the magnification of the mirror.

Given that;

Object distance (u) = -24cm;

Image distance (v) = -12cm (image is in front of mirror hence v is negative).

Now;

Magnification =

⇒ Magnification =

∴ Magnification is -0.5. Which tells that image is real and inverted and half of the size of the object.
