Answer #1

a) fromthe two graphd (cm) vs x(cm) is the shapshot graph. so the answeris A)left b) sincein history of the graph at time increases the wave moving forward direction the waveistravelling in+ve X-axis so the answeris B)right c) fromthe left graph wave length(3)cm-3c2cm 0.02m fromthe right graph the time (t)-50ms 30ms 20ms 0.02 sec velocity (v)- v 1.0ms a 0.02m t 0.02s
