Here are a number of statements concerning the refractive power of lenses. which of these statements are false? a. a positive refractive power means that a lens always creates an image that is larger than the object. b. two lenses with the same refractive power have the same focal lengths. c. a lens with a positive refractive power is a converging lens, whereas a lens with a negative refractive power is a diverging lens. d. two lenses with different refractive powers can have the same focal length. e. the fact that lens a has twice the refractive power of lens b means that the focal length of lens a is twice that of lens b.
