7.1 When there are two traveling waves of the same wavelength and frequency (hence the same velocity) in phase: fA (x, t) A sin(kx- ot) fs (x, t) B sin(kx ot) then it's clear that the actual wave you observe is fa B fA (x, t)+ fs (x, t (A B) sin(kx-ot) due to superposition principle. Namely, you observe the same wave form, except now the amplitude is A+ B. Now consider there are two waves of the same wavelength...

7. Consider two waves traveling in the same direction but with two slightly different angular frequencies ω- Δω and ω+ 2Δο. Let the fields have the same amplitude and polarization. a. Show the sum of the two waves is equivalent to a wave moving with a phase velocity vp-ωΚ but with an amplitude envelope which moves with a group velocity b. In the limit that Δω 0 the group velocity vg-do/dK. For waves traveling in a plasma we derived the...
