A physicist drives through a stop light. When he is pulled over, he tells the police officer that the Doppler shift made the red light of wavelength 640 nm appear green to him, with a wavelength of 545 nm. The police officer writes out a traffic citation for speeding. How fast was the physicist traveling, according to his own testimony? m/s

A physicist drives through a stop light. When he is pulled over, he tells the police officer that the Doppler shift made the red light of wavelength 650 $\mathrm{nm}$ appear green to him, with a wavelength of 520 $\mathrm{nm}$ . The police officer writes out a traffic citation for speeding. How fast was the physicist traveling, according to his own testimony?
