- A 6.25 mm high firefly sits on the axis of, and 12.9 cm in front of, the thin lens A, whose focal length is 6.79 cm. Behind lens A there is another thin lens, lens B, with a focal length of 23.9 cm. The two lenses share a common axis and are 56.3 cm apart. a) Is the image of the firefly that lens B forms real or virtual?. b) How far from lens B is this image located? Express the answer as a positive number. c) What is the height of this image? Express the answer as a positive number. d) Is this image upright or inverted with respect to the firefly?In the following three scenarios, an object is located on one side of a converging lens. In each case, you must determine if the lens forms an image of this object. If it does, you also must determine the following. whether the image is real or virtual whether the image is upright or inverted the image's location, q the image's magnification, M The focal length is f = 60.0 cm for this lens. Set both q and M to zero if no image exists. Note: If q appears to be infinite, the image does not exist (but nevertheless set q to 0 when entering your answers to that particular scenario).
