basic properties of waves

    λ - wavelength
    ν - temporal freq
    v - wave speed 
    A - amplitude

k the spatial frequency, i.e., 1/λ, or the wave number, the nubmer of crests in a unit length, so to speak.

ω the (angular) temporal frequency

not taking the time to solve things out in this run, unless I run into something I'm not familiar with.
