1. How would you represent a transverse wave and a longitudinal wave using physics students as your medium? Discuss amongst yourselves… Be prepared to demonstrate!

2. Wave properties cont.

3.  Associated with wave’s energy ◦ Proportional to the square of the amplitude ◦ Bigger amplitude  more energy  Measured from the equilibrium point (where the medium is at rest) to the maximum displacement

5.  Period (T) ◦ The time it takes for a wave to complete a whole cycle ◦ Measured in seconds  Frequency (f ) ◦ Number of complete oscillations a wave makes every second ◦ Units: hertz (Hz)  1 Hz=1/s ◦ f = 1/T

7.  Wavelength ( ) ◦ Length of one full wave ◦ Measured from crest to crest (peak to peak) or trough to trough

8.  How fast the wave moves through the medium  Depends on the medium the wave moves through  Can use http://phet.colorado.edu/sims/wave-on-a-string/wave-on-a-string_en.html
