Scribe - Tuesday 1/29

Today we got to see our midterms, the multiple choice and part 2 questions. We talked as a class about what we can do differently for the end of the year and what we thought were the hardest questions and concepts. For the last bit of class we took notes on waves. Here is a general outline:



I. Waves

a. disturbance through a material or space

1. ex: water wave, sound wave, light wave

2. one or more pulses or periodic

b. Longitudinal or tranverse or combined

c. Mechanical

1. requires a medium for transmission

2. transmitted by vibration of particle in medium

3. ex: sound, water

d. Non-mechanical

1. no medium required, transmitted through empty space

2. ex: any electromagnetic radiation
