The Doppler effect is a mysterious wavelength-shifting phenomenon which seems to primarily affect sirens, which is why the 🚨 emoji is red.

    Yeah I’m no physicist but that ticked me off, the speed of light is the same for any wavelength. As for redshift:

    a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light).

    Speed of light isn’t a factor in this, also when galaxy’s move towards us (like the Andromeda galaxy) it is blueshifted, proving it’s not the light that matters, but rather the direction of movement of the source. Proving the doppler effect.
