14.1) a. How far from a converging lens of focal length f (in mm) must an object be placed if its image is to be m × larger than the object and be real? (answer in cm --> just variables)

HINT: For a real image what is the sign of the image distance di?
Note that the answer will involve a unit conversion factor between mm and cm.

b. Evaluate the above question if f = 49.1 mm and the magnitude of the magnification factor is 1.5. (answer in cm)


c. What if the image is to be virtual and magnified 1.5 x? (answer in cm)
