1. ### Fourier Transform

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

3. ### Fourier Transform

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...
4. ### Modified Ampere's law

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!!!!
5. ### Modified Ampere's law

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...
6. ### Deriving Conditions for D field

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
7. ### Deriving Conditions for D field

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...
8. ### Electric energy of a dielectric sphere

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...
9. ### Electric energy of a dielectric sphere

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...
10. ### 2 of 2-Trig

cheers for that I shall be pondering on this later on Thanks
12. ### Different views

A good way to understand this is probably to read up about the wave/partical duality. This should be applicable for all text books. 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...
