A spaceship is traveling at a velocity of 0.6c towards a planet which is emitting light waves of frequency 6 x 10^14 Hz. If the wavelength of the light waves is 5 x 10^-7 m, what will be the frequency and wavelength of the light waves as observed by an observer on board the spaceship? Determine also the distance between two consecutive wave crests as observed by the observer.
