Astar is 1.302 parsecs away, NASA believes they can send a craft to the star at a speed of 0.2c 1) How long would the trip take take if measured by a clock on earth? 2) How long would the trip take from the perspective of the craft? 3) What is the distance between the Earth and the star as measured by the craft? 4) If a radio signal with a wavelength = to 10 cm is sent from the craft to Earth every month, (measured by a clock on the craft). What wavelength would the receiver on Earth need to be tuned to and how frequently would the signals arrive?
