Light Reflection and Refraction

NCERT In Text

 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, ho= h

Then, height of the image, hI= - 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.
