Question

The height of an object is 5 cm and the magnifica
tion of the image produced by a convex mirror is 06
cm. Find the height of the image​

Answer 1

Answer:

Given,. m= -v/u=0.5

U=-25 cm

So, m=-v/-25=0.5

v=12.5

Now using mirror formula.

1/v+1/u=1/f

1/12.5+1/-25=1/f

2.5/62.3=1/f

f=25 cm.

So, the required focal length of the mirror is 25 cm.
