Traveling Waves-start with Harmonic Waves, exciting with a simple harmonic motion of frequency f, wavelength ? = v/f
Traveling Waves-start with Harmonic Waves, exciting with a simple harmonic motion of frequency f, wavelength ? = v/f
We have seen that the travelling wave travels with speed v, so in full generality the wave function is (NON-DISPERSIVE):
and the harmonic wave excited by SHM is
Note k is called “wave number” and has nothing to do the the k in Hooke’s law used in the previous slide on SHM!!
It is useful to write the wave function in some other ways:
