The given graph (Fig.) shows the displacement versus time relation for a disturbance travelling with velocity of 1500 m s^ –1 . Calculate the wavelength of the disturbance.

From the graph Time period, T = 2 10^ -6 s. Frequency, v=1 T =5 10^5Hz. Wavelength, = u v =5 10^5m.

The given graph (Fig.) shows the displacement versus time relatio…
