LECTURE 12
     questions after lecture

for the wave lectures the best thing is to try these again

• QUESTIONS BEFORE LECTURE 12

now think about these

• If you can answer the questions before lecture, then you've learned what I wanted you to learn. Many of the words are from Lecture 12, but some aren't introduced until Lectures 13 or 14. The question about how common examples of waves differ from each other is one you can now answer using correct language about media, transverse, frequency, wavespeed, etc.
• What lecture demonstrations or examples in lecture illustrated all those words which label wave properties?
• What does Marshall McLuhan's statement, "The medium is the message" mean?
