WebRed-shift For visible light, red has the longest wavelength and violet the shortest. If the wavelength is longer than expected this is called a red-shift. If a source of waves is moving away the wavelength appears longer. A red-shift in the light from a star shows that the distance between us and the star is increasing. WebMore distant galaxies show a bigger red-shift. The red-shift shows that the galaxies are moving away from each other, and more distant galaxies are moving away faster. Therefore, the Universe is ... downloads 2018
