One end of a nylon cord of length 1.20m is tied to a rigid wall while the other end is free to move. Transverse waves travel along the cord with a speed of 48ms−1. The cord is set into its lowest possible stationary mode that satisfies these boundary conditions.
(a) Calculate the frequency required to excite this mode.
(b) How many antinodes are formed on the cord in this situation?
(c) Determine the distance of the nearest node from the fixed wall.
