Phase difference Definition and 155 Threads

if i have two sinusoidal waveform that are out of phase.. is it possible to calculate the phase difference knowing the frequency and time interval between the peaks of the waves? im sure it is but I am stumped on how to go about it. I am sure its quite easty.. any ideas? thanks very much...

Pardon the pun, but what's the difference between path difference and phase difference (when talking about interfering light waves)?

Can anyone explain the following to me; what is phase difference and coherence? what actually is diffraction and why does it happen (is it something to do with Huygens principle?) why do you observe circular fringes when using the Michelson interferometer your help is much...

A simple question. I though Maxwell said that : 1. The change of electric field generates magnetic field. 2. The change of Magnetic field generates Electric field. So, simple algorithm tells me there shall be a 90 degree of phase difference between the peaks of E field and B...

Hi i posted here before and got great help, and I ran into another problem maybe you can help me this is the question. Two loud speakers are placed on a wall 2.00 m apart. A listener stands 3.00m from the wall direclty infront of one of the speakers. A single ocillator is driving the speakers...
