Presentation Transcript

  1. Starter 1/f = 1/do + 1/di If an object is very far away from a positive lens, how are the focal length and the image distance related?

  2. This Lens Equation 1/f = 1/do + 1/di Part I Science Notebook Entries: A. Describe carefully what the terms in the thin lens equation stand for. B. For an object very far away, how is the focal distance related to the image distance?

  3. This Lens Equation 1/f = 1/do + 1/di Part II Experiment A. Determine the focal length of your positive lens by choosing an object that is very far away ( across the room) and projecting an image on a screen. Record this value with the correct units. B Put your lens on the optics bench and test the thin lens equation by obtaining an image and measuring do and di and describing the image. Repeat for another larger or smaller image. Use your data to calculate f and M for each trail in part B. Show all of your calculations in your report. Put a biconvex lens on the bench and attempt to obtain an image. Explain your results. E. Repeat A, B, and C for a different positive lens.

  6. Lab Questions 1. A slide projector uses a positive lens to project an image on a screen for viewing. Why are the slides loaded upside down in the projector? 2. A positive lens projects an image on a screen. How would the image change if ½ of the lens was covered by black paper? ( Try it out.) 3. Can you project an image on a screen with a single negative lens? Explain.
