Hello everyone,
I was just thinking about something...A police radar gun measures the speed of an object by the change in frequency of the reflected wave. For example...we might have a gun sending out a series of radio waves towards an object moving toward us like this...
GUN: )____)____)____)____)____)____)______<-object<-
in which case we would receive the following series of waves since each wave reaches the object more quickly:
GUN: (_(_(_(_(_(_(_______<-object<-
however, it seems that there should be no Doppler shift if the speed of light were constant. The waves should hit the object at the same rate, no matter what the speed of the object.
