An enlarged image is formed behind a spherical mirror at a distance of
15cm for an object placed in front of it. The focal length of the mirror is
25cm. Find out the magnification 'm' of the image and also find out the
object distance. Draw a ray diagram.

Answer:
m = (-1.6)
object distance = 9.4 cm
Explanation:
F = 25 cm
v = -15 cm
u = ?
m = ?
From,
1/F = 1/u +1/(-v)
» 1/25 = 1/u - 1/15
» 1/u = 1/25 + 1/15
» 1/u = (3+5)/75
» 1/u = 8/75
» u = 75/8
» u = 9.375 cm
Now,
m = v/u
= -15/9.4
= -1.6
