An object is placed 15.0 cm to the left of a double-convex lens of focal length 20.0 cm. The image of this object is located.​

Answers

Answer 1

The image of this object is located at -60 cm. The formula for the mirror equation is used in the given problem.

What is a mirror equation?

A mirror equation is an equation that relates object distance and image distance to focal length.

The given data in the problem is;

Image distance (u) = 15 cm

Object distance (v) = ?

f is the mirror's focal length=20 cm

The mirror equation is given as;

[tex]\rm \frac{1}{v} +\frac{1}{u} =\frac{1}{f} \\\\ \rm \frac{1}{v} =\frac{1}{20} -\frac{1}{15} \\\\ \frac{1}{v} = 0.01666 \\\\\ v=-60 \ cm[/tex]

Hence, the image of this object is located at -60 cm.
