Question
A transverse wave is travelling along a horizontal string. The first picture shows the shape of the string at an instant of time. This picture is superimposed on a coordinate system to help you make any necessary measurements. The second picture is a graph of the vertical displacement of one point along the string as a function of time. How far does this wave travel along the string in one second?
Options
A.0.3 cm
B.3.0 cm
C.9.0 cm
D.27 cm
Solution
Sol. λ = 9cm. T = 3sec, f = 1/3
vw = λf
= 3 cm/sec
