A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located ?

Answer»

SOLUTION :Distance of object from concave MIRROR u = -10 cm
As magnification of image is 3 and image is REAL, hence m = -3
`because""m = -(UPSILON)/(u)`
Hence, `upsilon = - mu = -(-3) (-10) = - 30` cm
Thus, image is formed 30 cm in front of the concave mirror.
