Q. Determine the ray-transfer matrix for an optical system made of a thin convex lens of focal length f and a thin concave lens of focal length -f separated by a distance f. Discuss the imaging properties of this composite lens?
Q. A 20x telescope has a 12-cm diameter objective lens. What minimum diameter should the eyepiece lens have to collect all the light rays from an on axis distant source?
A computer is reading data from a rotating CD-ROM. At a point that is 0.030m from the center of the disk, centripetal acceleration is 120m/s2. What is the centripetal acceleration at a point that is 0.05 m from the center of disc.
Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.
