Monday class 10/24 canceled

Folks - I have a last-minute family crisis to tend to and must cancel class for tomorrow evening.  (Nothing too terrible, but my presence is needed.)

I'm so sorry about this!  

Practice problems and answers are posted. I will add more notes in the next few hours.

Please also review the notes on waves, particularly the sites linking to E/M spectrum pages.

See you Wednesday - email me if you have any questions.

Sincerely,

Sean Lally
