An object is a distance 15.6cm to the left of a diverging lens ("Lens 1") with a focal length of -19cm. Lens 1 is itself a distance 29cm to the left of a second diverging lens ("Lens 2") with a focal length -19cm.

The object is along the optical axis of the two-lens system.

How far is the image of the object due to Lens 2 away from Lens 2? Note that in this case the light has passed through Lens 1 first. Answer in cm.

If the image is to the left of Lens 2 your answer should be negative, and if it is to the right of Lens 2 your answer should be positive.
