Source vs. Medium • Consider: • Period • Wavelength • Frequency • Wave speed • Which can be changed if the source changes in some way? • Which can be changed if the medium changes in some way?
Source vs. Medium When I change the speed at which the machine moves, which of the following will change? • Frequency, period, wavelength, and wave speed all change • Frequency, period and wavelength • Frequency and wavelength • Wavelength and wave speed • Frequency and period
Waves review • Wave displacement depends on where AND when (x and t)! • What are we graphing anyway? Check out “longitudinal traveling wave” application; Link on web page!
Total Phase Which of the following includes only points with a total phase of exactly/2? • All • ABC • ADG • AEH • ACF
Total Phase Which of the following includes only points with a total phase equivalent to /2? • All • ABC • ADG • AEH • ACF
Fixed Phase Constant Which of the following lists only points with a fixed phase constant of exactly to/2? • All • ABC • ADG • AEH • ACF
Mathematical relationships & Model Tools: • Making sense of the wave equation: • Using Total Phase Charts:
