7 Two people look at the same object through the same microscope. Person A is nearsighted, and person B is farsighted. How do the magnifications of the object seen by Person A and Person B though the microscope compare? MA and MB denote the magnifications for Person A and Person B, respectively. A MA MB B MA MB C MAK Me D not enough information is given

Explanation / Answer

magnification of microscope = ( D /fe) (- L/f0)

where f0- focal length of objective

fe = focal length of eyepiece
L = tube length

And D = is the near point for eye

For nearsighted person: D = 25 cm ( problem docusing on distant object)

for farsighted, D > 25 cm

hence MB > MA
