A Galilean telescope is constructed by an objective of focal length 50 cm and an eyepiece of focal length 5.0 cm. (a) Find the tube length and magnifying power when it is used to see an object at a large distance in normal adjustment. (b) If the telescope is to focus an object 2'0 m away from the objective, what should be the tube length and angular magnification, the image again forming at infinity?
