Source vs medium
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 medium1
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
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!
