Destruction of students' rationality in Divine Albert's world: The following video teaches that, when the observer starts moving towards the light source, "wavelengths are going to condense and so the frequency is going to be higher". Yet a transient note informs the student that "the wavelengths themselves do not actually condense, they just appear to condense to the observer":

Doppler effect for electromagnetic waves

Needless to say, wavelengths' strange behavior - they do not condense but appear to condense so that the observer could measure the same speed of the waves, Divine Einstein, yes we all believe in relativity, relativity, relativity - occurs only in Divine Albert's world. In a world different from Divine Albert's world the wavelength would be independent of the motion of the observer and the frequency shift in light waves, just like the frequency shift in sound waves, would be caused by a shift in the speed of the waves as measured by the observer:

http://faculty.washington.edu/wilkes/116/slides/Physics116_L08-interference.pdf
"Sound waves have speed c, and f and L are related by c=Lf. For an observer moving relative to medium with speed u, apparent propagation speed c' will be different: c'=c±u. Wavelength cannot change - it's a constant length in the medium, and same length in moving coordinate system (motion does not change lengths). Observed frequency has to change, to match apparent speed and fixed wavelength: f'=c'/L."
