Astronomers have developed a method call interferometry, which uses separate tele- scopes to observe the same object at the same time to achieve very high angular resolution. If astronomers use an interferometer observing the wavelength of 1000 nm to measure the angular diameter of a planet like Jupiter orbiting a star 10 light-years from Earth, how far apart are the telescopes?
