5.2 Show that the light from a source which is moving away from us with a speed of 0.6c has twice the wavelength it has in the frame of reference of the source. 5.3 A spaceship moves with speed V relative to an observer O, on a straight line which passes very near the observer. A source on the spaceship emits light of wavelength lo = 500 nm in the frame of reference of the spaceship. For what range of the spaceship's speed will the light be visible to the observer? The wavelengths of visible light stretches from 2A Ans.: -0.22 <ß<0.33 400 nm to 2B 700 nm, approximately. %3D 5.2 Show that the light from a source which is moving away from us with a speed of 0.6c has twice the wavelength it has in the frame of reference of the source. 5.3 A spaceship moves with speed V relative to an observer O, on a straight line which passes very near the observer.
