Consider a plane wave with rigth-hand circular polarization
travelling in the +y direction in a nonmagnetic lossless dielectric
material. The dielectric constant of this material is 4. The
frequency of the wave is 100 MHz and the electric field amplitude
is 3mV/m. Find the instantaneous expression for E.
I need a clear explanation for this question.

Suppose a sinusoidal wave on a string, having amplitude A and
travelling in the −xˆ direction, is partially reflected at the
point x = 0, so that the reflected wave is in phase with the
incident wave at x = 0 but has amplitude kA, where 0 ≤ k ≤ 1 is the
reflection coefficient. a) Show that each point on the string
undergoes simple harmonic motion and determine how the amplitude of
the simple harmonic motion varies with x...

With a plane wave, I always took the direction of the
wavevector, k, as the direction of propogation (magnitude
proportional to the inverse wavelength). Alternatively, it could
represent the momentum (minus a factor ?) of a particle.
However inside a crystal, the electron wavevector and the
electron velocity are not necessarily in the same direction. I'm
thinking here of a 2D material with a cylindrical Fermi surface
where the momentum may have a z component, but the Fermi velocity
does...

Hello, I am wondering how I can determine the direction in which
a wave is travelling given a function I must verify if it first is
a solution to the wave equation by finding the partial derivatives
then I do not know how to extrapolate the direction and speed of a
wave. Thanks
