Analogous of theta in waves

  1. Dec 31, 2013 #1
    I want you note this comparation:
    [tex]\\ \sin(\theta)=\sin(\omega t)=\sin(2\pi f t)=\sin\left(\frac{2\pi t}{T}\right) \\ \\ \sin(?)=\sin(k x)=\sin(2\pi \bar{\nu} x)=\sin\left(\frac{2\pi x}{\lambda}\right)[/tex]
    ω is rate of change of θ with respect to t. So, exist a physic/mathematical quantity that when derived with respect to x results the quantity k?

    The wave number k = 2π / λ

    Wavenumber is the analogous of omega. I'm asking by analogous of theta.
