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 50.0 cm and the near point in his right eye is 100 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 Hint: Go back to basics and use the thinlens equation to solve part (b).
