Guest Posted April 4, 2008 Report Share Posted April 4, 2008 How fast do you have to be driving your Porsche before you can honestly say to the cop, "That red light looked green to me!" Neither you or the cop is colorblind. "Red" is defined as light with a wavelength of 650 nanometers, and "green" is defined as light with a wavelength of 510 nanometers.

0 Guest Posted April 4, 2008 Report Share Posted April 4, 2008 Not sure of the exact speed, but just looking at the problem, I would say maybe about ~95% of C or so? Don't have any numbers yet Quote Link to comment Share on other sites More sharing options...

0 EventHorizon Posted April 4, 2008 Report Share Posted April 4, 2008 Definitely driving at an unsafe speed....so the officer should give you a ticket for speeding. And if the fine grows linearly (or more) with speed....I'd say you should have gotten the ticket for running a red light instead! Quote Link to comment Share on other sites More sharing options...

0 Guest Posted April 4, 2008 Report Share Posted April 4, 2008 (edited) after looking into it more, it looks like it might be a lot less than I originally thought. Maybe around .30c. making somewhere around 200 million miles per hour? Or maybe I messed up some calculation Edited for an error Edited April 4, 2008 by Noct Quote Link to comment Share on other sites More sharing options...
0 bonanova Posted April 4, 2008 Report Share Posted April 4, 2008 0.238 c where c=3x108 m/s. Her speedometer read about 159,549,917 miles/hour. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted April 5, 2008 Report Share Posted April 5, 2008 the windshield is tinted green Not quite. You can actually change how things look according to your speed. Much like when you're sitting in a racing arena, you hear the cars drive by you and as they do you actually hear them at a high pitch then it goes down. But if you ask the driver, the sound is the same the whole way. This is due to the Doppler effect. This same effect also holds true for light. If things are moving away from you then they are "red shifted", or they appear more red then they actually are. If things are moving towards you (or you towards them) they get shifted towards the higher end of the spectrum. Quote Link to comment Share on other sites More sharing options...
