Initially the observer is stationary in the beach water but then starts walking out into the ocean with a speed v. Relative to him, the frequency of the ocean waves shifts from f=c/L to f'=(c+v)/L and their speed shifts from c to c'=c+v.
Initially the observer is stationary with respect to the sound source but then starts moving towards the source with a speed v. Relative to him, the frequency of the sound waves shifts from f=c/L to f'=(c+v)/L and their speed shifts from c to c'=c+v.
Initially the observer is stationary with respect to the light source but then starts moving towards the source with a speed v. Relative to him, the frequency of the light waves shifts from f=c/L to f'=(c+v)/L and their speed shifts from c to c'=....? Einsteinians?
Einsteinians' initial reaction: Help! Help! Divine Einstein! Yes we all believe in relativity, relativity, relativity!
The next day Einsteinians want to know who's asking the question:
