1. A red photon has a wavelength of 660 nm. How fast must a star be moving toward the Earth for a red photon emitted by the star to change its color to an orange photon of wavelength 620 nm? You may, if you wish, express your answer either in m/s or in terms of the speed of light c (e.g., "0.021c"). [You'll need to do a little bit of algebra. Keep in mind that, by convention, the velocity...
