When an object is placed 110 cm from a diverging thin lens, its image is found to be 55 cm from the lens. the lens is removed, and replaced by a thin converging lens whose focal length is the same in absolute value as the diverging lens. this second lens is at the original position of the first lens. - what is the magnitude of the focal length for these lenses? - where is the final image of the object?

Explanation:

Given that,

Object distance u= -110 cm

Image distance v= 55 cm

We need to calculate the focal length for diverging lens

Using formula of lens

Put the value into the formula

The focal length of the diverging lens is 36.6 cm.

Now given a thin lens with same magnitude of focal length 36.6 cm is replaced.    

Here, The object distance is again the same.

We need to calculate the image distance for converging lens

Using formula of lens

Here, focal length is positive for converging lens

The distance of the image is 54.85 cm from converging lens.

Hence, This is the required solution.
