Your task in physics lab is to make a microscope from two lenses. One lens has a focal length of 12 , the other a focal length of 4.5 . You plan to use the more powerful lens as the objective, and you want its image to be 16 from the lens, as in a standard biological microscope.How far should the objective lens be from the object to produce a real image 16 from the objective? What will be the magnification of your microscope?
