EINSTEINIANA: DANGEROUS ANALOGIES
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: http://game2gether.de/wordpress/wp-c...4-1024x819.jpg Pentcho Valev |

EINSTEINIANA: DANGEROUS ANALOGIES
"Pentcho Valev" wrote in message ... For all waves (light waves included), when the observer starts moving towards the wave source with a speed v, the speed of the waves relative to him shifts from c to c'=c+v: No. This is not true for light waves. http://math.ucr.edu/home/baez/physic.../velocity.html or http://en.wikipedia.org/wiki/Velocit..._of_relativity both provide the correct formula. |
