Electromagnetic Waves and their Spectrum

[Helena van Mierlo]

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.
