A wave is described by y = 0.0198 sin(kx - ωt), where k = 2.00 rad/m, ω = 3.52 rad/s, x and y are in meters, and t is in seconds.?

I know that the amplitude is 0.0198 m but how do I find the wavelength, frequency and speed?

    wavelength λ = 2π/k = 2π / 2.00rad/m = 3.14 m

    frequency f = ω/2π = 3.52rad/s / 2π = 0.560 Hz

    speed v = fλ = 0.560Hz * 3.14m = 1.76 m/s
