A person decides to use an old pair of eyeglasses to make some optical instruments. He knows that the near point in his left eye is 40.0 cm and the near point in his right eye is 98 cm.
(a) What is the maximum angular magnification he can produce in a telescope?
(b) If he places the lenses 10.0 cm apart, what is the maximum overall magnification he can produce in a microscope?
(Go back to basics and use the thin-lens equation to solve this part.)
