PGH Conceptual Physics Lab 82

Introduction The purpose of this lab is to investigate the nature, position, and size of images formed by a converging lens. If the lens is at the focal point, then the image will be inverted because the image will be real but not visible. Procedures 1. Collect the converging lens, lens holder, the meter stick, the meter stick holders, the note card, and the night-light with a clear, 7-watt bulb. 2. Plug in the light bulb, place …showed first 75 words of 727 total…

The information we discovered supported our hypothesis because when the lens was at its focal point, the image was inverted but not visible. The most fallible areas most likely to cause measurable experimental error are that the human eye cannot detect when the lens is perfectly at the focal point, which would also lead to measurement errors. This could have changed the focal length, therefore altering the rest of our results.
