Although sound travels quite fast, it is still possible to calculate its speed in air. To do this, the time it takes a sound to travel a measured distance must be recorded. Either the distance ...

For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.
