The aperrture of the largest telescope in the world is about 5 m. if the separation between the moon and the earth is 4xx10^(5)km and the wavelength of visible light is 5000 Å, then the minimum separation between the objects on the surface of the moon which can be just resolved is approximately equal to

Two luminous point sources separated by a certain distance are at 10 km from an observer. If the aperture of his eye is 2.5xx10^(-3)m and the wavelength of light used is 500 nm, the distance of separation between the point sources just seen to be resolved is
