## Question

The aperture of the largest telescope in the world is 5 m. if the separation between the moon and earth is 4 × 10^{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:

### Solution

50 m

As limit of resolution and if *d* is the distance between objects on the surface of moon which is at a distance *r* from the telescope,
