Question: 135 according to the doppler effect of light the...

Question details

. (1.35) According to the Doppler effect of light, the perceived wavelength Ap of a light source with a wavelength ofA, is given by: λ,-, -, where c is the speed of light (about 300-10 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 530 nm and red wavelength is 630 nm.
