In a ripple-tank experiment a surface water wave has a wavelength of

4.0\,\text{cm}

and completes one oscillation in

1.5\,\text{ms}

. Answer the following questions: (i) Convert the given wavelength and period into SI base units. (ii) Calculate the speed of the wave in

\text{m\,s}^{-1}

. (iii) Express the same speed in

\text{cm\,s}^{-1}

in standard scientific notation.
