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.
