    Great video. I can't find the next video referenced to in 9:32... Is it up on this channel?

    can you also give an explaination of how does the DBR reflectors work? THanks

      Ah this is such a great topic! Much of my Ph.D. is actually on distributed Bragg reflectors. I've added it to the list.

    why dont we consider also the wavefront in the middle?

    Hello, are these explanation also valid for an flexural wave propagating in a elastic plate ? Thank you !

    Great video! I have a question about the reason why the wave can not construct with other fraction to infinity is that the wave in the waveguide is not a plane wave, according to your video. So if there are two waves in free space which are discribed as sin and -sin, they interfre with each other and get totally canceled. Will it happen or not? Does the process obey energy conservation? Thank you!

      Hi Ryan, I can try to answer your questions.
      In free space if two waves meet each other, one sin and the other - sin they canceled, because in each point(in space time) they have the opposite value.
      For the conservation of energy there aren't problem because the avarege value don't change, in INPUT we have sin that have 0 as avarege, and in output again 0. This is only an intuitive explanation, analytically you have to consider the area of the signal for the energy and not the avarage value.

      ​@@davide8228Thanks for your detailed answering! Now, I have some new perceptions about this questions which I came up with a year ago. And I want to share it with you.
      Recent, I learned a numerical software for simulating electromagnitic wave propagation called FDTD. I ejected two plane waves, which have a totally opposite
      amplitude. I set a monitor to record the propergation of two wave. No electric field is observed.
      So, it is just what you say, the two waves canceled. They did not disappear but propagate in the space at the totally oppsite pace.
