Guidelines for Making notes (Section 2.1 and 2.2)

By now I have assigned all my classes (except for the Advanced Learners) to make notes for sections 2, 2.1 and 2.2. Below are some hints to help you with your note making:

Section 2
- What is a transverse wave?
- [The two main types of transverse waves are not necessary. However, you do need to have some general idea what the EM waves are, and that they are transverse waves]
- What is a longitudinal wave?

Section 2.1
- How do the particles move in a transverse wave?
- What is a crest? A trough?
- [Point 3,4,5,6,7 are repeat concepts of what has been covered earlier in section 1.2. However, read them first to make sure that you have already covered that concept earlier]
- How do you determine the direction of particle movement?
- What does the displacement-position graph describe?
- [Everything on Oscillation belongs to the previous Unit and not here. Make notes only if you feel this is necessary to help you understand waves]

Section 2.2
- How do the particles move in a longitudinal wave?
- [all the diagrams are illustrations of longitudinal waves. Draw them only if you feel they help you understand and remember this concept]
- What is a compression?
- What is a rarefaction?
- How do you measure wavelength in a longitudinal wave?
- [Point 8: the two kinds of amplitude is not important]
- How do you sketch a displacement-position graph for longitudinal waves?

By the way, the sub-heading for Section 1.1, 1.2 and 2.3 is "Properties of Progressive Waves"
The sub-heading for Section 2, 2.1 and 2.2 is "Transverse and Longitudinal Waves".

Or whatever sub-headings you so please. This is just a suggestion. You know what? I want you to come up with your own sub-headings. If you copy my sub-headings I will scold you. I want to force you to be creative. Muahahaha. =P
