diffraction limit is the minimum angular separation needed for two sources to distinguish by the telescope. in this case, radiations from stars have different wavelength and so their diffraction limit also varies with that. so the small wavelength radiations will have small diffraction limit so that they are hard to distinguish.
Calculate the theoretical diffraction-limited resolution of a 10m telescope at wave- lengths of 300 nm (UV)...
A scientist requires the construction of a diffraction-limited telescope to image small dunes on Mars. The telescope will be mounted on a spacecraft instrument platform. The spacecraft will orbit Mars at an altitude of 400 km. The dunes are 2 m in diameter (horizontal size, as seen from above). The wavelength of instrument operation is 500 nm. The large-format detector is a CCD with 4096x4096 array of pixels, where each pixel is 30x30 microns in size. The scientist requires that...
