An aerial photograph of the area is taken from an airplane flying at an altitude of H = 5 km. What focal length f and lens diameter D of a camera should be chosen in order to photograph objects of size l ~ 2.5 cm on photographic film with a resolution of n = 500 lines/mm? For what time t should the camera shutter be opened (exposure) so that the movement of the aircraft at a speed of V = 360 km/h does not lead to blurring of the image?
