Question

An object is placed 25 cm from a convex lens whose focal length is 10 cm. The image distance is ________ cm.

Answer 1

16.67cm

Explanation:

Given parameters:

Object distance, U = 25cm (u is -25cm for convex lens)

Focal length = 10cm

Unknown parameter:

Image distance, V = ?

Solution

   To solve for the image distance, we use the equation:

Images in a convex mirrors are real, inverted, smaller than the object

          $\frac{1}{f}$   = $\frac{1}{v}$  - $\frac{1}{u}$  

 

$\frac{1}{10}$   = $\frac{1}{v}$  - $\frac{1}{-25}$  

            image distance = 16.67cm
