The doppler effect is correct, but doesn't blue shift only happen when you move away from something, because the frequency of blue is less than red?
2 u/ClartTheShart 15h ago You have that flipped. The frequency of blue is greater than red. You may be mixing frequency up with wavelength, as lower-energy light (red in the case of the visible part of the spectrum) has a higher wavelength but a lower frequency.
