Two converging thin lenses (f1 = 15 cm and f2 = 20 cm) are separated by 25 cm. A

candle is placed in 40 cm in front of the first lens.

a) Where will the image of the candle be created by the two-lens system?

b) Describe the properties of the image.

c) Describe how the image changes as the lenses are moves closer together.

d) The lenses are now moved right next to each other. What is the equivalent optical

power of the system (optical power = reciprocal of the focal length. In this case, it will

be the focal length of the two-lens system)? What conclusion can you draw?

You have two lenses with focal lengths of f1=+150 mm and f2=+75 mm. Use these lenses to design a compound microscope. Use the 75 mm lens as the objective to produce an intermediate image with a magnification of –3. At what position with respect to the lens should the object (specimen) be placed? The 150 mm lens will be the eyepiece. What is the magnification of the eyepiece? Where should the eyepiece be placed with respect to the intermediate image?...
