Document Summary
8:19 pm: lenses page 1, lenses page 2, lens system. An object 5 cm high is located 75 cm from a converging lens (x1 = 75 cm) of focal length f1 = 50 cm. A second converging lens of focal length f2 is located 200 cm from the first lens (x2 = 200 cm). An image of the object is to be formed on a screen 200 cm from the second lens (x3 = 200 cm). What must be the focal length f2 of the second lens so that the final image appears on the screen: lenses page 3, single lens system. A lens located in the y-z plane at x = 0 forms an image of an arrow at x = x2 = 78. 8 cm. The tip of the object arrow is located at (x,y) = (x1, y1) = (-46. 3 cm, 3 cm). The index of refraction of the lens is n = 1. 54.
