According to the Doppler effect of light, the perceived wavelength ? p , of a light source with a wavelength of ? s is given by: λ P = λ S 1 − v c 1 + v c wherec is the speed of tight (about 3 00 × 1 0 6 m/s) and v is the speed the observer moves toward the light source. Calculate the speed the observer has to move in order to see a red light as green. Green wavelength is 530nm and red wavelength is 630 nm.
