Adiverging lens (f1 = -12.0cm) is located 50.0 cm to the left of a converging lens (f2 = 34.0 cm). a 2.0 cm-tall object stands to the left of the diverging lens, exactly at its focal point. determine the distance of the final image relative to the converging lens in centimeters.

The final image relative to the converging lens is 34 cm.

Explanation:

Given that,

Focal length of diverging lens = -12.0 cm

Focal length of converging lens = 34.0 cm

Height of object = 2.0 cm

Distance of object = 12 cm

Because object at focal point

We need to calculate the image distance of diverging lens

Using formula of lens

The rays are parallel to the principle axis after passing from the diverging lens.

We need to calculate the image distance of converging lens

Now, object distance is ∞

Using formula of lens

The image distance is 34 cm right to the converging lens.

Hence, The final image relative to the converging lens is 34 cm.
