An object is placed at a distance of 15 cm from a convex lens of focal length 20 cm. List four characteristics (nature, position, etc.) of the image formed by the lens.

Answer :


Object distance u = -15 cm

Focal length of convex lens f= 20 cm

Image distance v=?

We know that lens formula is:

Substituting the values in this formula

v = -60 cm


Height of image = 4×height of object

● Image is formed on the same side of the object above the principal axis.

● It is virtual and erect.
