Question

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 ?

Answer 1

The magnification(m) is given as = -3 (as image is real)

object distance(u) = -10 cm

image distance (v)=?

we know that m= -v/u

-3 = -v /-10

-3 = v/10

v =-3 * 10

v = – 30 cm

thus, the image is 30 cm away from the concave mirror
