1.	A concave mirror produces three times magnified real image of an object placed at 10 cm in front of it. Where is the image located ?
Answer» Magnification produced by a spherical mirror is given by the relation, `m=("Height of the Image")/("Height of the Object")= -("Image Distance")/("Object Distance")` `m=(h_(1))/(h_(0))= -u/v` Let the height of the object, `h_(0)` = h Then, height of the image, `h_(1)` = −3h (Image formed is real) `(-3h)/(h)=(-v)/u` v/u=3` 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.
