What are its wavelength and frequency?

  1. Jul 12, 2008 #1
    A wave travels with speed 200m/s. Its wave number is 1.5rad/m. What are its wavelength and frequency?

    distance = wavelength x # of wavelengths

    1m = 1.5 (lamda) since in 1 meter there was 1.5 waves. 1/1.5 = 0.66m

    200 = 0.66 (f); f = 300Hz.

    But this is wrong. I don't know why...
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Re: Waves

    How many radians are there in a single cycle (wavelength)?
