Question

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

Answer 1

Explanation:

Given magnification m=3

and object distance u=10 cm and we know,

Magnification m=

u

−v

−v=3×−10

v=30 cm

Thus the image is formed at distance of 30 cm.

Answer 2

m= -3 (real image)

u =-10cm

m = -v/u

v = -m * u

v = - (-3) * (-10) = -30 cm

image is at 30cm in front of mirror.
