For the telescope described the telescope is in normal adjustment (i.e., when the final image is at infinity)? A small telescope has an objective lens of focal length 140cm and an eyepiece of focal length 5.0cm. What is the separation between the objective lens and the eyepiece?
b. If this telescope is used to view a 100 m tall tower 3 km away, what is the height of the image of the tower formed by the objective lens?
c. What is the height of the final image of the tower if it is formed at 25cm?
