The power of a converging lens is 4.5 D and that of a diverging lens is 3 D. The power of this combination of lenses placed close together is:

The power of a combination of two lenses X and Y is 5 D. If the focal length of lens X be 15 cm: a) Calculate the focal length of lens Y. b) State the nature of lens Y.

Two lenses A and B have focal length of +20 cm and, -10 cm, respectively. a) What is the nature of lens A and lens B? b) What is the power of lens A and lens B? What is the power of combination if lenses A and B are held close together?
