Need help with the following question.   A sinusoidal wave is travelling on a string under tension T = 8.0(N), having a mass per unit length of w = 0.0128(kg/m). It’s displacement function is D(x,t) = Acos(kx - wt). It’s amplitude is 0.001m and its wavelength is 0.8m. It reaches the end of this string, and continues on to a string with w = 0.0512(kg/m) and the same tension as the first string. Give the values of A, k, and w, for the original wave, as well as k and w the reflected wave and the transmitted wave.
