  • Electricity & Magnetism + Quantum Mechanics?

    Updated: 2012-12-31 21:49:10
    Hi! I've recently completed my first semester of college and it's offered me some insights. For example.... the world is three-dimensional and, as such, multidimensional calculus exists! I...

  • Determine the polarity of the reflected EM wave.

    Updated: 2012-12-31 21:23:04
    Attached are the drawings. Does the polarity *E*of depend on [itex] \Gamma =\frac {\eta_2-\eta_1}{\eta_2+\eta_1}[/itex] So if [itex]\eta_2

    *1. The problem statement, all variables and given/known data* This is just a request to have some guidelines. Does anyone have a clue as to how to estimate the relative permittivity ε of a...

  • Discrete Wavelet Transform and filterbanks

    Updated: 2012-12-31 19:26:46
    Please, can someone explain to me why filterbanks followed by downsampling are equvalent to the application of a wavelet transform (maybe with simple terms, if it is possibile)? Thank you very...

  • What is the Weak Force

    Updated: 2012-12-31 19:07:12
    I know there are four different forces in the universe and they all affect us. I know that gravity is the force of objects' mass interacting I know electromagnetic is the force carried by photons...

  • Effect on current, if a higher voltage is applied

    Updated: 2012-12-31 18:45:41
    I'm confused over this because generally i'm told that if the voltage increases then so does current and this satisfies the equation:V=IR because I=V/R increasing the top of the fraction should mean...
