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 ...

whilst a guitar string plucked gently makes a soft sound. Wavelength is the distance between each crest of the wave. Frequency is how many waves there are per second. The higher the frequency, the ...

A gap width similar to the wavelength of the waves passing through causes a lot of spreading, eg sound waves passing through a doorway. A gap width much larger than the wavelength causes little ...

The approach uses high-frequency sound waves, usually in the megahertz (radiofrequency ... modulate its intensity or sensitively tune its wavelength, albeit over a narrow wavelength range.
