... (A) The amplitude is A. (Recall that the amplitude of y = sin(x) is just 1, not 2.) (B) How exactly does the argument of sin make it a traveling wave? Well, a traveling wave keeps the same waveform at all times. Thus, the overall argument has to be constant. ωt−kx = constant ⇒ x ∝ −constant + ωt. Th ...

Thus, a discussion of energy flow of either an antenna or of scattering by a conducting sphere that is based on the total Poynting vector will consider these two problems to be similar.

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
