Question

6. A positive thin lens of 10 cm focal length is followed by a negative thin lens of $-5$ cm focal length. The distance between the two lenses is 5 cm. Show that this is a zero-power system, using the graphical ray-tracing rules of this chapter. 8. Repeat Problem 6, but with a negative lens, $K = -0.1 \text{cm}^{-1}$, and a concave mirror, $r = -15$ cm, located 5 cm behind the lens.

Step 1

According to the graphical ray-tracing rules, a ray of light parallel to the principal axis will pass through the focal point on the other side of the lens. So, draw a ray parallel to the principal axis and after passing through the lens, it will converge at the Show more…
