3. The objective lens of a refracting telescope has a focallength of 9.5 m.
Please help me break down and work through this practicequestion so that I can better under the steps and work it out on myown.
3. The objective lens of a refracting telescope has a focal length of 9.5 m. a. What is the refractive power of this lens? b. What focal length eyepiece is needed for the magnification of the telescope to be 500x? C. If a converging lens with a focal length of 7.0 m is placed next to the objective lens what is the total refractive power and the focal length of the combined lenses?
Please help me break down and work through this practicequestion so that I can better under the steps and work it out on myown.
