The wavelength, \(\lambda\), of a wave is the ... 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 ...

For different types of waves — such as electromagnetic waves, sound waves or water waves — the wavelength can vary significantly. The concept applies to any periodic wave where the pattern ...

Using high-frequency sound waves to make tunable optical filters ... that allows users to precisely and rapidly control the wavelength, amplitude and propagation direction of a laser beam.

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.
