WebRed Shift and Blue Shift When the light source moves away from the observer, the frequency received by the observer will be less than the frequency transmitted by the source. This causes a shift towards the red end of the visible light spectrum. Astronomers call it the redshift. 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. WebThe Universe.
