# Find the Nature, Position and Magnification of the Images Formed by a Convex Lens of Focal Length 0.20 M If the Object is Placed at a Distance Of: 0.25 M - CBSE Class 10 - Science

ConceptRefraction of Light Image Formation by Lenses - Convex Lens

#### Question

Find the nature, position and magnification of the images formed by a convex lens of focal length 0.20 m if the object is placed at a distance of:

0.25 m

#### Solution

u = -25 cm
f = 20 cm

1/f=1/v-1/u

1/20=1/v-1/-25

1/v=1/200-1/25

1/v=(5-4)/100

1/v=1/100

v=100 cm

The image will be formed at a distance of 100 cm behind the mirrror.Magnification,

m=v/u

m=100/-25

m=-4

Magnification is negative, which means the image is real and inverted.

Is there an error in this question or solution?
