The Moon was photographed with a telescope, the objective of which had a diameter of 20 cm and focal length of 150 cm. The exposure time was 0.1 s. (a) What should the exposure time be, if the diameter of the objective were 15 cm and focal length 200 cm?(b) What is the size of the image of the Moon in both cases?

the same A certain telescope has an objective mirror with an aperture dlameter of 210 mm and a focal length of 1 890 mm. It captures the Image of a nebula on photographic film at its prime focus with an exposure time of 1.55 min. To produce the same light energy per unit area on the film, what is the required exposure time to photograph the same nebula with a smaller telescope that has an objective with a 50.0-mm diameter...

A Galilean telescope is made with a 40 cm focal length objective lens and a -10 cm focal length eyepiece. As is typical, the separation between the lenses is the sum of the focal lengths, i.e. 30 cm. Usually this telescope would be used to view far distant objects, but suppose the object viewed is only three focal lengths (120 cm) distant from the objective lens (a) On the figure above, sketch the principal rays that determine the size and location...
