WebRed-shift is observed when the spectral lines from the distant galaxy move closer to the red end of the spectrum This is because light waves are stretched by the expansion of the universe so the wavelength increases (or frequency decreases) This indicates that the galaxies are moving away from us WebIn fact, Hubble noticed that the light from the galaxies was red-shifted. Dark lines (signatures of elements) in light waves are shifted towards the red end of the spectrum: … WebThis is called a red-shift because the spectrum of light is shifted towards the red part of the spectrum. The light waves are squashed together if the star or galaxy is moving towards Earth. The wavelength of the waves is reduced. This is called a blue-shift because the spectrum of light is shifted towards the blue part of the spectrum. how is the diving in oahu in january
