Experiments to Find the Speed of Waves on Water Using a Ripple Tank

The video tutorial explains how to measure the speed of waves on water using a ripple tank. It covers the equipment needed, including a vibrating beam and a lamp, and describes the process of setting up the experiment. The tutorial demonstrates how to measure the frequency and wavelength of the waves by observing shadows and using a ruler. Finally, it shows how to calculate the wave speed using the formula v = F * Lambda, emphasizing that the results are estimates.
