The institute of space and astronautical science in japan proposes to place a radio telescope into an even higher orbit than the halca telescope. using this telescope in concert with a ground-based radio telescope, baselines as long as 25,000 km may be obtainable. astronomers want to use this combination to study radio emission at a frequency of 43 ghz from the molecule silicon monoxide, which is found in the interstellar clouds from which stars form. (1 ghz = 1 gigahertz = 109 hz.) (a) what is the wavelength of this emission? (b) taking the baseline to be the effective diameter of this radio-telescope array, what angular resolution can be achieved?
