I got this question, A wave with a frequency of 10 hertz moves at 360 m/s. Part (a) What is the wavelength of the wave? Part (b) What is the period of the wave? I treated this as a deep water wave, and used the equations, c2 = gl/(2pi) w2 = gk c = w/k to find the wavelength and period of the wave. But I never used the frequency given (which would imply a period of 0.1 sec) and instead got a period of 231 sec. Is there something I'm missing? Is it possible to solve the above question without using deep water equations?
