Can any of you help. I am trying to fight a speeding ticket with a written declaration. To be honest I feel it was so unfair I was going with the speed of traffic and marked me as going 6mph more. I am sending the court explaining how I believe this was wrong and a radar error. Taking Physics 101 in college and not really good at it as I'm just learning but feel like I can win if I explain this correctly. If my wave velocity is 71mph, Source of velocity is -1 (being the cop with his gun) what would be my source of frequency f0 ? Also does is makes sense that the doppler effect is affected if there's other cars so close and around me and therefore his gun is inaccurate? I'm traveling in a caravan with 5 cars behind me and 4 cars so close in front.. I hope I win this court battle as I'm a good citizen and feel so unfair. 65mph limit and I was going 71mph. Plus I'm a broke college student.
