Step 1
We need to find the speed at which a red light (with a wavelength of 665 nm) would appear as a green light (with a wavelength of 540 nm) due to the Doppler effect. The Doppler effect describes how the observed frequency (and thus wavelength) of a wave changes due Show more…

How fast would you have to drive in order to see a red light as green? Take $\lambda=630$ nm for red and $\lambda=530 \mathrm{nm}$ for green.
How fast must you be traveling relative to a blue light $(480 \mathrm{nm})$ for it to appear red $(660 \mathrm{nm}) ?$
How fast would a motorist have to be traveling for a yellow (λ = 590 nm) traffic light to appear green (λ = 550 nm) because of the Doppler shift? Explain
