Basically it explains the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.
when the observer is also moving in the same direction as the source of the sound wave the effect would be magnified...
Physics are annoying huh?
I know I wish someone would just post the vid already.
Thanks to the DGAF"s , way to posibly keep my kids from being able to race there in the future. I hope BLM or Casey just takes action like Arizona did on the two campers that broke the rules and left a campfire and it started our biggest wildfire ever ,instead of closing the forrest down to all campers. Guess being to wide and stabbin a tire at post tech is minimal now.
Overkill is Underrated.
