Work out the system matrix for the composite element shown below and use it to answer the following questions. (a) What is the optical power of this composite element? The optical power P is defined as 1/f. (b) If a plane wave is incident from the left, where will it focus? 1cm n=1 n=1 n=1 (c) This system is used to image an object at infinity. Is the image real or virtual? n=3/2 n=3/2
