The transverse displacement of a string (clamped at its both ends) is given by `y(x, t) = 0.06 sin((2π)/3x) cos (120 πt)` where x and y are in m and t in s.The length of the string is 1.5 m and its mass is `3.0 ×10^(–2)` kg. Answer the following : (a) Does the function represent a travelling wave or a stationary wave? (b) Interpret the wave as a superposition of two waves travelling in opposite directions. What is the wavelength, frequency, and speed of each wave ? (c) Determine the tension in the string.
