Usually vector E and H are made up and constant (eg E0) multiplied by phase and time dependent parts. You must time average these non-constant parts of the equation. Often this comes down to time-averaging the square of sine/cosine, which gives a multiplicative factor of 0.5.
I understand that certain vectors in space-time (spacelike vectors) present a non-causal situation where E2 which takes place at a time after E1 in the rest frame cannot physically be a consequence in a different frame at sufficient speed. but there is also the relationship that arises from the...
Im attempting a problem in relativistic optics that's asking me to write k_x, k_y and k_z in terms of lambda, c, and theta (theta being the angle between a source and an observer, at rest relative to each other). Lamda is the wavelength in this reference frame. I started off using trigonometry...
no i have not taken this into account. you mean that they are oscillating not just on one axis but in several directions? this could be the case. each metal bar is attached at each end to two long nylon wires. the wires are at high tension but there could be some extension and contraction in the...
Hello,
I am currently working on a lab in which we are studying the behaviour of chain of metal bars attached together with nylon wire in such a way as to to mimic the ability of solids or liquids to transmit a wave.
After studying the normal modes of the system as well as the quality...
Hello guys,
I'm having some trouble getting my head around the method of images, partly due to confusing notes and things.
If I have a charge +q at a fixed point (0,0,a) above a conducting plane that is held at zero potential, it is said that the plane can be replaced with a charge of -q...
