A spy satellite circles Earth at an altitude of 200 km and carries out surveillance with a special highresolution telescopic camera having a lens diameter of 35 cm. If the angular resolution of this camera is limited by diffraction, estimate the separation of two small objects on Earth's surface that are just resolved in yellow-green light ( = 550 nm).
