Yes that would be great. (By the way the info given is not the real results because the real results are classified!) I need to be able to see if they are indicative of noise! Thanks

Hi there, I have a range of results from scanning a piece of metal of length L. The results from the scan are %FSH of the oscilloscope. I have to analyse the noise of the signal and thought I'd do this using a Fourier transform. Using the range of results as follows could you please tell me...

To be honest with you that isn't much help at all really. Why post something if you don't know the answer? A cat makes a meow sound by the way!

Hi I was wondering if you can help me. How is the concept of the displacement current used to resolve the ploblems with the application of Ampere's law. I know that the modified ampere's law is curl(B)=Mew(0)(jc+jd) I just know how the displacement current jd is used to solve the...

The question stated is a question on a past exam paper, I am trying to review these questions. I need to derive the boundary counditions satified by D at the interface between 2 media Please help Thanks hhh79bigo

Hi there, I was wondering if anyone would be willing and able to help me with this question. Q. Derive the boundary condition satisfied by D at the interface between 2 media. I know that the D field is continuous at the suface, but I need to be able to derive this. If anyone can...

I don't fully understand, do i have to use maxwells equations to find the charge density, and if so how does this apply to a dielectric between 2 capacitor plates. I thought that the E field would be E(0)/EPSILON(r) where E(0) is the Electric field of the capacitors without the dielectric...

Electric energy of a dielectric sphere! Hi there, I have attempted a question, I was just seeing if some one can go over it and check if it is ok! Q. The Electric field E inside a dielectric sphere placed between the plates of a large parallel-plate capacitor is uniform. Given that the...

Radians and degrees? What is the answer?

cheers for that I shall be pondering on this later on Thanks

A good way to understand this is probably to read up about the wave/particle duality. This should be applicable for all textbooks. Like TD said, radiation, behaves like waves and particles. Its a parradox that is very important in modern physics. Its not much help but its something tht needs...

Total energy of a dielectric sphere please help! I have a problem that I can not do after searching the net and looking through my notes and textbook. I think it is a basic electomagnetic field question but i just can't get my head around it. The question is: The electric field E inside...

Most of the theoretical physicists at my university are actually in the maths department. But it depends on what you want to do with it that matters

Yet!
