A camera lens with focal length f = 50 mm and maximum aperture f>2 forms an image of an object 9.0 m away. (a) If the resolution is limited by diffraction, what is the minimum distance between two points on the object that are barely resolved? What is the corresponding distance between image points? (b) How does the situation change if the lens is âstopped downâ to f>16? Use λ= 500 nm in both cases.

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (Ï = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
