Question
Two graphs of the same harmonic wave are shown below. The graph (1) on the left shows the displacement of wave y, as a function of position x for a given instant of time. The graph (2) on the right shows the displacement of wave as a function of time 't' for a given position. The speed of the wave is
Options
A.5.0 cms–1
B.0.5 cms–1
C.0.4 cms–1
D.4.0 cms–1
Solution
Sol. ν = $\frac{\lambda}{T} = \frac{(4.0 - 0)cm}{(0.8 - 0)s}$ = 5.0 cm/s
