Is there any way to find rough focal length of concave lens and convex mirror without using convex lens? Though I did the experiments(with object and image needles, not candle) very carefully with no parallax errors during my practical class, my readings are incorrect. I want to know if der s way to find out rough focal lengths of diverging lens n mirror in a simple way so that I can manipulate my readings accordingly during practical exam... Plzzzzzz help...
