A telescope on earth uses a circular mirror of diameter 10 m (that is the aperture diameter). how close to each other could two stars, that are 20 light years away from the earth, be in order for the telescope to resolve them using a wavelength of 500 nm? Express your answer in meters. hint: A light year is the distance that light travels in a year.
