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?
