Question

An object of highest 5 cm is placed at a distance of 25 cm from a concave mirror, if the radius of curvature of the mirror is 10 cm, then calculate
1) distance of the image from the mirror
2) height of the image
3) nature of the image
4) magnification

Answer 1

Explanation:

Given : u=−25 cm f=−10 cm h

o

=5 cm

Using

v

1

−

u

1

=

f

1

Or

v

1

−

(−25)

1

=

(−10)

1

⟹ v=−7.14 cm

Height of image

h

o

h

i

=

u

v

Or

5

h

i

=

−25

−7.14

⟹ h

i

=1.43
