(a) At x = 2.3 m and t = 0.16 s the displacement is () ( )() [ ] ( , ) 0.15sin 0.79 2.3 13 0.16 m = 0.039m. yxt =− (b) We choose y m = 0.15 m, so that there would be nodes (where the wave amplitude is zero) in the string as a result. (c) The second wave must be traveling with the same speed and frequency. This implies 1 0.79 m k = , (d) and 13 rad/s
