Hi B. R.,

Some things you can add to your list:


1. Show the limits to the series of normal modes for the driven standing
waves; show the low frequency limit; Show the high frequency cutoff.
2. Show how the normal mode frequencies are different for the open ended
case of standing waves and the close ended case of standing waves.
3. Before showing impedance matching, show partial transmission and
partial reflection.

You can get this classic, excellent Teaching Book on Amazon:

Similarities in Wave Behavior: Teacher's Edition (The Bell Telephone
Laboratory Series) [Paperback]
by John N. Shive

My Best to you from the States,
- Jerry
