The key distinction is that a fixed lens has a single, unchangeable focal length, while a motorized zoom lens has the capability to vary its focal length.

Two thin lenses of focal lengths \(\mathrm{f}_{1}=-50 \mathrm{~mm}\) and \(\mathrm{f}_{2}=+100 \mathrm{~mm}\), respectively, are separated by \(50 \mathrm{~mm}\). What is the focal length of the combination? Where are the principal points of the combination?

Thick lens

Three lenses with focal lengths of \(+10 \mathrm{~cm},-10 \mathrm{~cm}\), and \(+10 \mathrm{~cm}\), respectively, are placed one behind the other, \(2 \mathrm{~cm}\) apart. If parallel light is incident on the first lens, how far behind the third lens will the light come to a focus?
