A floating leaf oscillates up and down two complete cycles in one second as a water wave passes by. The wave's wavelength is 10 meters. Beats are produced when two tuning forks, one of frequency 240 hertz and the other of frequency 246 hertz are sounded together. A skipper on a boat notices wave crests passing the anchor chain every 5 seconds. The skipper estimates the distance between crests is 15 m.
More information is needed.
All of the above are transverse waves. None of these are transverse waves. When you tune a radio to a certain station, you match the frequency of the internal electrical circuit to the frequency of the frequency of the wanted radio station. An explosion occurs 34 km away.
