Yep, typo? Not sure how that got messed up. I think I fixed it.

Nodes and Antinodes

Hello :)

Are nodes and antinodes confused in this explanation?

The peaks become troughs (nodes) and vice versa, but the points with zero displacement (antinodes) stay in the same place, i.e. they do not travel.

Hello,
This work is a good summary and information for IB learners.
I will advise to my students.
You may add more figure to explain topic .

Thanks many.

Common "wrongs" in physics with their explanations. Includes some advice as how NOT to lose marks in exams.

Thanks for the added info. The notes have been updated.

Units for Activity

An addition to the notes; the unit for 'activity' (decays per second, near the end) is the Becquerel (Bq). 1 Bq = 1 nuclear decay per second. Thanks.
