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...

When light waves of the same frequency overlap, interference phenomena can be observed. In this problem two plane waves with the same angular frequency w but different wave vectors ki/2 nterfere as shown below. The waves are given by Ev/2 E1/2e)z, where E1/2 are real amplitudes. The wave vectors are and k-2n/λ is a constant wave number. 2 of the total field Ε = El-E, Hint: Remember that a) Calculate the intensity I(i ặcol in complex notation |ä2* b) Now...
