54. 54 What are you here to Learn? Understand the past

55. 55 What are you here to Learn? Understand the past Doppler shift – Color (light) determined by wavelength (in meters).

56. 56 What are you here to Learn? Understand the past Doppler shift – Color (light) determined by wavelength (in meters). If the source of the light is moving, the wavelength (or color) will “shift” by an amount determined by the speed of the source.
