Homework Help: Wave Problems

  1. Dec 1, 2014 #1
    1. The problem statement, all variables and given/known data
    just wondering how we got T when the equation is V=fλ i assume that this is one oscillation.

    T=4.5x10-4
    F=?
    λ= 2.0x10⁵cm

    2. Relevant equations
    V=fλ
    F=1/T



    3. The attempt at a solution

    F=1/4.5x10-4
    F=22 hz

    v= fλ
    v= (22) (2.0x10⁵)

    v=4400000 m/s

    Please post the full problem statement. I don't understand what you are asking.
