Two lenses are mounted d = 39 cm apart on an optical bench. The focal length of the first lens is f1 = 9.8 cm and that of the second lens is f2 = 3.1 cm. An object of height ho = 4.9 cm is placed at a distance of do = 24 cm in front of the first lens. Now consider the two-lens system and the final image it forms, i.e., the image created by the second lens. What is the distance, in centimeters, between the object and its final image? D =?

A typical human eye is nearly spherical, and is usually about 2.5 cm in diameter. Suppose a person first looks at a coin that is 2.4 cm in diameter and located 34.0 cm from her eye. Then, she looks up at a friend who is 1.8 m tall and 4.00 m away. Find the magnitude of the approximate size of each image (coin ℎI,coin and friend ℎI,friend) on her retina. (Hint: Just consider rays from the top and bottom of the object that pass through the center of the lens.) b) Are the images on her retina upright/inverted and/or virtual/real?

There is a lens combinations between two converging lenses that have focal lengths of f1=13 cm (lens 1) and f2=16 cm (lens 2). They are separated by 56 cm along a horizontal line. There is a lit candle (height ho) placed 36 cm in front of the lens 1 (f1=13 cm). Thus, the separation between the candler and the second lens (f2=16 cm) is 92 cm Please calculate actual postion of final image. Is it real/imaginary?
