Problem: A refracting telescope is used to view the Moon (diameter 3480 km, distance from Earth 385,000 km). The focal lengths of the objective and eyepiece are +2.45 m and +16.1 cm, correspondingly.
Part I: What should be the distance between the lenses?
m
Part II: What is the diameter of the image produced by the objective?
cm
Part III: What is the angular magnification?
If possible just a brief explanation how you got the answer?
