Lab #4: The Telescope
Pre-LabName:______________________________ Date: ___________________ Section: __________1) What is the Lens Equation? What do o i and f stand for in the equation?2) What are the five parts of the Optical Bench used in this experiment? Briefly describe what each part does.3) Describe the procedure for measuring the focal length of a lens. 4) What are the most important things to keep in mind in order to get a more accurate measurement of the focal length?5) Extra Credit: The lenses in a telescope perform two jobs: gathering light and magnifying the image. Can a mirror with the same curvature as a lens do the same two jobs? Why? Lab #4: The Telescope
