A wave has an amplitude of 0.25 m, a frequency of 5 Hz and a wavespeed of 4 m/s.a.
(a) Write the displacement equation for the wave.
(b) Use a graphing calculator to produce 5 snapshot graphs of the wave at t = 0, 0.05, 0.1,0.15, 0.2 s. Sketch the resulting graphs.
(c) Use a graphing calculator to produce a history graph of the wave for position x=0.5 m.Sketch the resulting graph
(d) Briefly describe how you could use the graphs from b. to produce the graph from c.
