Sure, go ahead! I assume that the phone will operate with any signal level, as long as it isn't zero. Is there a simplified expression that solves directly for the intensity of the waves, that you know of?

Thanks guys What I am trying to apply this to, is the calculation of the wave intensity of an electromagnetic wave when it passes through a Faraday's cage, which is unable to successfully shield from all radiation. In testing this, I have placed a phone inside a metal box, and slowly...

Hi I was just wondering if anyone knew a forumla for calculating the power intensity of waves, when diffracted through a circular aperture? I have searched all over the net, but cannot find one which solves for the power intensity of the wave directly.

We know that the ball should move because the problem (see above) states that it should. Which direction it moves in is also unknown, though I assume it could roll either way. I am not sure whether any factor affects it's tendency to move right or left, and no experimentation so far has...

Homework Statement Put a hot metal ball on parallel horizontal rails. The ball starts to move. Investigate the phenomenon. Homework Equations I have found two equations, one exponential and one linear relating the expansion of the rails and the ball to the temperature increase...
