Hi Vargo, Thanks for your help - I think doing it in terms of the angle probably makes more sense than x-y co-ordinates. I did give it a go but it doesn't seem to be working out for me. I got: thA = t / 2pi thB = (ft + j) / 2pi thC = (gt + k) / 2pi We can solve for t for the condition...

This is a problem that a few friends and I came up with while working on an extra-curricular robotics project: There are three gears meshed together with idle gears inbetween so that the three gears rotate in the same direction. http://puu.sh/2knXq The gear ratio between gear A has 4 teeth...

I'm not sure about maxwell's equations, but I think I've sorted out the problem by using E=V/d (Electric Field = Voltage / Distance) which has provided me a suitable answer. Thanks for all your help!

Thanks lanedance for the link. I read it, and I've already covered the stuff in that page, what I am trying to find is an equation that will tell me what E equals (E as in the electric field strength, NOT the energy of the wave). A photon does not have a charge, so E = f/q is an...

That is the energy in the wave, not the energy in the electric field! There is energy in the magnetic field as well isn't there?

I have been desperately trying to find an equation (or a set of equations where I can derive an equation) that shows a relationship between the energy in an electric field and the wavelength or frequency of an electromagnetic wave. I am trying to show a relationship between Wavelength and...
