Alens that is "optically perfect" is still limited by diffraction effects. suppose a lens has a diameter of 130 mm and a focal length of 680 mm . part a: find the angular width (that is, the angle from the bottom to the top) of the central maximum in the diffraction pattern formed by this lens when illuminated with 600
part b: what is the linear width (diameter) of the central maximum at the focal distance of the lens?

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
