5. The Doppler effect applies to light waves as well as sound waves. Astronomers use this to measure the motion of stars and galaxies. In 1929, Edwin Hubble
discovered that light from distant galaxies was shifted away from the blue end of the spectrum and towards the red end of the spectrum Red light has a longer
