Ray Optics Q2: Find Focal Length of Mirror

AI Thread Summary
To find the focal length of the mirror, the discussion centers on a 2.0-cm tall object that produces a 1.0-cm tall upright image located 165 cm from the object. The initial attempt at solving the problem yielded an incorrect focal length of 37 cm. Participants are prompted to clarify the equations used in their calculations and the rationale behind their attempts. The conversation emphasizes the need for correct application of mirror formulas to determine the focal length accurately. Understanding the relationship between object height, image height, and distances is crucial for solving this optics problem.
