Unformatted text preview: 4. Compute the image location and magnification of an object 30 cm from the front lens of the thin lens combination shown in the figure. Do the calculation by finding the effect of each lens separately and make a sketch of the appropriate rays. 5. Using geometry and the diagram below left, calculate the focal length of the mirror in terms of a, b, and L for two cases: a) screen outside the focal length (as shown in the diagram), b) screen inside the focal length (not shown, so create a new sketch). 6. Using geometry and the diagram above right, find the focal length of the diverging lens in terms of h 1 , h 2 , L and x. 10 cm f 1 =+30 cm f 2 =20 cm object mirror screen a b L lens h 1 x L h 2...
