Today classes reviewed wave concepts such as wavelength and amplitude, plus looked at the difference between S (transverse) and P (longitudinal) waves.
With S waves, the medium (what the wave is passing through) vibrates perpendicular to the direction of a wave. (Side to side motion)
With P waves, the medium vibrates in the same direction as the wave (front and back).
We looked at examples plus some phenomena when waves interact using the Slinky; more on this later when we look in-depth at waves. Also, most classes got practice calculating the speed of a wave when given wave length and frequency (waves per second)
Tonight's homework: Read p. 288-293
Due tomorrow: p. 293#1-6
*** Since no PLAN test tomorrow, this is due for all classes ***
