Optics
You combine two thin lenses by placing them in contact so that their axes coincide, forming what is called a compound lens. The focal lengths of the lenses are cm and − cm, respectively. Find the focal length of this compound lens. Does this compound lens act as a diverging lens, as a converging lens, or it cannot be determined?

Optics and Converging & Diverging Lenses 1. What is the relationship between the curvature of a lens (thick vs thinner converging lenses) and its light-bending power? 2. Focal length: is there a trend in the image distances vis a vis focal lengths as the object distance gets larger? What happens to the thin lens formula when object distance is very large? 3. In the compound lens formula, 1/fcomp = 1/f1 + 1/f2, why does a longer focal lens will not...
A converging lens is placed at x 0, a distance d 11.5 cm to the left of a diverging lens
A converging lens is placed at x 0, a distance d 11.5 cm to the left of a diverging lens as in the figure below (where F and Fo locate the focal points for the converging and the diverging lens, respectively). An object is located et x-1.90 cm to the left of the converging lens and the focal lengths of the converging and diverging lenses are 4.50 cm and -8.60 cm, respectively. (a) Determine the x-location in cm of the final...

Two systems are formed from a converging lens and a diverging lens, as shown in parts a and b of the drawing. (The point labeled "Fconverging" is the focal point of the converging lens.) An object is placed inside the focal point of lens 1 at a distance of 7.30 cm to the left of lens 1. The focal lengths of the converging and diverging lenses are 15.00 and -20.0 cm respectively. The distance between the lenses is 50.0 cm....
