Did you complete the reading assignment? (Typically this means at least 20-30 minutes looking over the assigned sections of the book.)
yes no

If a vibration is made to happen at a natural oscillating frequency of an object, this is called:
beats
harmonics
resonance
standing waves
traveling waves

true
false

A flute and a clarinet both play the same note. Two microphones record the sound wave oscillations. T/F: If the oscillations picked up by the microphones are graphed, the two graphs will look the same.
true
false

(Review question.) Ralph is confused by the difference between standing waves and beats, because they are both caused by interference of waves. Help Ralph understand when interference will produce one rather than the other.

The comments in the next next two boxes go into a big, mostly anonymous text file that I skim through before the morning lecture, using the comments to help me plan class discussion. ("Mostly anonymous", because I can track down who made what comment, but it takes some effort on my part to do so.) Therefore, if you really want to make sure I see your question/comment and answer it individually, you should send it to me via email and not through this form.

Which part of today's assignment was particularly hard or confusing? What would you like to spend extra time on in class?
