Hello, I am reading over the topic of converging and diverging lenses, and I had a question relating to phenomena of image formation as seen through these. Based on the ray diagrams that are typically used (freshman physics) how does one conclude whehter or not an image is inverted or upright? I know that a real versus virtual images depends on whether or not you have a convergence of the rays upon the focal point, but I am not sure about the former. Any insight would be wonderful! Thank you!
