A concave mirror produces three times magnified (enlarged) real image of object placed at 10 cm in front of it. Where is the image located?
Magnification produced by a spherical mirror is given by the relation,
Let the height of the object, `h_0=h`
Then, height of the image, `h_1=-3h`(image formed is real)
Object distance, u= – 10 cm
v = 3 × ( – 10) = – 30 cm
Here, the negative sign indicates that an inverted image is formed at a distance of
30 cm in front of the given concave mirror.
