Angular Resolution
An astronomer wants to determine whether or not he or she can photograph Castor and Pollux at the same time on a 5 x 8 inch plate using a lens system with a 1200 mm focal length. If the two stars are approximately 5 degrees apart, will it be possible to make the photograph?
Optics/Physics
Predict the size of the image of Jupiter if photographed at opposition with a lens having a focal length of 9600 mm. (Assume Jupiter is a disk of 1.43 x 10^5 km and is 6.29 x 10^8 km from the Earth.)
