Question

11 of While Galileo did not invent the telescope, he was the first known person to use it astronomically, beginning around 1809. Five of his original lenses have survived (although he did work with others). Two of these have focal lengths of 1710 mm and 960 mm Review I Cong How long would this telescope be between the two lenses? Express your in answer in meters to three significant figures. VO AE ? Submit Best A Part What is the greatest angular magnification that allo could have obtained with these lenses? (Note: Galileo actually obtained magnifications up to about 300 x. but by using a diverping lens as the eyepiece) Express the magnification to three significant figures

please answer b-d, thank you!
