The general wave function describing a sinusoidal one-dimensional traveling wave is y(x,t) . The similar-looking function y(x,t)=Acos2(kx t) also describes a one-dimensional traveling wave, although it is not sinusoidal. What is the wavelength of this new wave? Select one: a. k b. 2k c. 2 d. k Clear my choice
