Asinusoidal wave is travelling on a string under tension t = 8.0(n), having a mass per unit length of ï­1= 0.0128(kg/m). itâs displacement function is d(x, t) = acos(kx - ï·t). itâs amplitude is 0.001m and its wavelength is 0.8m. it reaches the end of this string, and continues on to a string with ï­2 = 0.0512(kg/m) and the same tension as the first string. give the values of a, k, and ï·, for the original wave, as well as k and ï· the reflected wave and the transmitted wave.
