    Hi, thanks for this great material. There is a mistake in the first quiz. The distance between the peak and the trough is not the amplitude, but 2x the amplitude. Thank for correcting this.

      I noticed the same mistake. It’s still not corrected.

        I thought I was crazy when I got it wrong.

    The assertion “All three are related mathematically such that if you know one, you can calculate the other two using this equation: c=lambda * freq” is wrong.

    Please, correct it with:

    If you know 2 of these 3, you can calculate the other one.

    Thank you.

      Dear Alvaro,
      thank you for your hint, that was a typo, and exactly what we meant :).
      We just corrected it.
