Is this image upright or inverted with respect to the firefl

Reference no: EM13262804

A 5.61-mm-high firefly sits on the axis of, and 10.3 cm in front of, the thin lens A, whose focal length is 6.99 cm. Behind lens A there is another thin lens, lens B, with focal length 27.5 cm. The two lenses share a common axis and are 59.9 cm apart. Is the image of the firefly that lens B forms real or virtual? How far from lens B is this image located (expressed as a positive number in cm)? What is the height of this image (as a positive number in mm)? Is this image upright or inverted with respect to the firefly?
