In a compound microscope, the objective consists of a focal length of around 0.73 cm, while the eyepiece consists of a focal length of around 1.7 cm. The separation among the objective and the eyepiece is L = 14.0 cm. The other microscope that consists of the similar angular magnification can be constructed by interchanging the two lenses, given that the distance among the lenses is adjusted to a value L'. Determine L'
